Vocab: Phone & internet — A1 ​

Phone & internet vocabulary at A1 level.

Maskulin Feminin Neutrum Plural

die Adresse — address; email address ​

Adresse can mean a physical address or an email address, often in the compound E-Mail-Adresse. With a person, German usually uses jemandem schreiben or jemandem eine Nachricht schicken, not a direct translation of English address.
Die Adresse steht auf dem Brief.
The address is on the letter.
steht auf dem Brief means is on the letter. Die Adresse is nominative because it is the subject, and the finite verb steht stands in position two.
Ich schreibe die Adresse auf den Umschlag.
I write the address on the envelope.
schreibe means write, and der Umschlag means envelope. Die Adresse is accusative because schreiben takes a direct object; auf den Umschlag is accusative because it expresses movement onto the envelope.
Ich schicke der Adresse eine Nachricht.
I send a message to the address.
schicke means send, and eine Nachricht means a message. Der Adresse is dative because it is the recipient of schicken, while eine Nachricht is the accusative thing sent.
Die Änderung der Adresse kostet nichts.
The change of address costs nothing.
die Änderung means the change, and kostet nichts means costs nothing. Der Adresse is genitive because it specifies which change; the finite verb kostet is in position two.
Wir haben drei Adressen gespeichert.
We saved three addresses.
drei means three, and gespeichert means saved. Adressen is plural and accusative because it is the object of haben ... gespeichert; the auxiliary haben is in position two and the Partizip II goes to the end.

an — on, switched on ​

As an adverb, an describes a device that is switched on or appears at the end of a separable verb such as anmachen. It is different from the preposition an, which is followed by a noun phrase.
Das Licht ist an.
The light is on.
das Licht means the light. an says that the light is switched on; after ist, it does not take an adjective ending and is not a preposition because it has no following noun.
Mach bitte den Fernseher an.
Please switch on the television.
mach bitte means please switch or make, and der Fernseher means the television. In the separable verb anmachen, an moves to the end in the imperative, while den Fernseher is accusative as the object.

anrufen — to call, to telephone ​

anrufen is separable: in a main clause, an moves to the end, as in ich rufe dich an. Its perfect uses haben, not sein, and the person called is accusative.
Ich rufe meine Mutter heute Abend an.
I am calling my mother this evening.
meine Mutter means my mother and heute Abend means this evening. meine Mutter is accusative because anrufen takes the person called as a direct object; the finite verb rufe is in position two and an goes to the end.
Ich habe gestern meinen Bruder angerufen.
I called my brother yesterday.
gestern means yesterday and meinen Bruder means my brother. meinen Bruder is accusative after anrufen; habe is the auxiliary in position two and angerufen closes the clause.
Sie rief mich nach der Arbeit an.
She called me after work.
mich means me and nach der Arbeit means after work. mich is accusative because it is the person called; in the simple past, rief stands in position two and an goes to the end.
Ruf mich später an!
Call me later!
später means later. mich is accusative because it is the person called, and the imperative keeps the prefix an at the end.
Ich würde dich morgen anrufen.
I would call you tomorrow.
dich means you and morgen means tomorrow. dich is accusative after anrufen; würde marks a hypothetical idea, while the complete infinitive anrufen stays at the end.
Wir werden dich heute Abend anrufen.
We will call you this evening.
wir means we and heute Abend means this evening. dich is accusative because anrufen takes a direct object; werden is in position two and the infinitive anrufen goes to the end.

anschalten — to switch on, to turn on ​

The prefix an is separable: schaltet an, but the infinitive and Partizip II stay together. The opposite is ausschalten.
Ich schalte das Licht an.
I switch on the light.
das Licht means the light. The finite verb schalte stands in position two and the prefix an moves to the end; das Licht is accusative because anschalten takes an accusative object.
Wir haben den Fernseher angeschaltet.
We turned on the television.
wir means we and der Fernseher means the television. The perfect uses haben plus angeschaltet, which stands at the end; den Fernseher is accusative because it is the object being turned on.
Sie schaltete die Heizung an.
She switched on the heating.
sie means she and die Heizung means the heating. The weak past form schaltete is in position two and an is separated to the end; die Heizung is accusative after anschalten.
Schalt bitte das Radio an.
Please switch on the radio.
bitte means please and das Radio means the radio. The informal imperative is schalt and the separable prefix an goes to the end; das Radio is accusative because it is the object.
Ich würde die Lampe anschalten, wenn es dunkel wäre.
I would switch on the lamp if it were dark.
die Lampe means the lamp, wenn means if, and dunkel means dark. The conditional uses würde plus the infinitive anschalten, which stays together at the end of its clause; die Lampe is accusative.
Er wird morgen den Computer anschalten.
He will turn on the computer tomorrow.
er means he, morgen means tomorrow, and der Computer means the computer. Future uses wird in position two and the complete infinitive anschalten at the end; den Computer is accusative.

die App — app, application ​

App is short for Applikation, but the short form is normal in everyday German. Do not confuse it with die Anwendung, which is more formal or technical.
Die App ist kostenlos.
The app is free.
kostenlos means free of charge. Die App is nominative because it is the subject, and the finite verb ist stands in position two.
Ich öffne die App.
I am opening the app.
öffnen means to open and ich means I. Die App is accusative because öffnen takes a direct object; with a feminine noun, the article looks the same in nominative and accusative.
Ich vertraue dieser App.
I trust this app.
vertrauen means to trust, and dieser means this. Dieser App is dative because vertrauen takes a dative object; the feminine dative article is dieser.
Die Funktionen der App sind praktisch.
The app's functions are practical.
die Funktionen means the functions and praktisch means practical. Der App is genitive because it shows which app the functions belong to; sind is the plural verb for Funktionen.
Auf meinem Handy sind viele Apps.
There are many apps on my phone.
auf meinem Handy means on my phone and viele means many. Meinem Handy is dative because auf describes a fixed location here, while viele Apps is plural and the subject of sind.

ausschalten — to switch off, to turn off ​

This verb takes an accusative object: etwas ausschalten means to switch something off. Its prefix aus- separates in a main clause, but the infinitive and Partizip II stay whole.
Ich schalte das Licht aus.
I switch off the light.
das Licht means the light. Das Licht is accusative because ausschalten takes a direct object, and the separable verb splits around the finite verb schalte.
Wir haben den Fernseher ausgeschaltet.
We switched off the television.
der Fernseher means television. Den Fernseher is accusative because it is the object, and the perfect uses haben plus ausgeschaltet, which stands at the end.
Sie schaltete die Heizung aus.
She switched off the heating.
die Heizung means heating. The noun phrase is accusative after ausschalten, and the weak past form schaltete is in position two while aus goes to the end.
Schalt bitte das Radio aus.
Please switch off the radio.
bitte means please and das Radio means the radio. This is the informal singular imperative, with omitted du; the direct object is accusative and the prefix aus is separated.
Wenn es zu laut wäre, schaltete ich die Musik aus.
If it were too loud, I would switch off the music.
zu laut means too loud and die Musik means the music. The form schaltete ... aus expresses a hypothetical action here; die Musik is accusative, and the prefix stays at the end.
Ich werde den Computer später ausschalten.
I will switch off the computer later.
der Computer means computer and später means later. Den Computer is accusative, while werde stands in position two and the complete infinitive ausschalten goes to the end.

der Benutzername — username ​

der Benutzername is a weak masculine compound noun: it has -n in the accusative and dative singular, as in den Benutzernamen and mit dem Benutzernamen. Its plural is also Benutzernamen.
Der Benutzername steht auf der Karte.
The username is on the card.
steht means “is written” or “is located,” and auf der Karte means “on the card.” Benutzername is nominative because it is the subject, and the finite verb steht is in position two.
Ich habe den Benutzernamen vergessen.
I forgot the username.
vergessen means “forgotten,” and ich habe means “I have.” Benutzernamen is accusative because it is the object of vergessen; this is a weak masculine noun, so it has -n outside the nominative singular.
Mit dem Benutzernamen kann ich mich anmelden.
I can log in with the username.
mit means “with,” and sich anmelden means “to log in.” Benutzernamen is dative because mit always takes the dative; kann is in position two and anmelden goes to the end with the modal verb.
Das Passwort des Benutzernamens ist sicher.
The username's password is secure.
das Passwort means “the password,” and sicher means “secure.” Benutzernamens is genitive to show possession, meaning “of the username”; the finite verb ist stands in position two.
Die Benutzernamen stehen in einer Liste.
The usernames are in a list.
stehen means “are” or “are located,” in einer Liste means “in a list.” Benutzernamen is the plural form, and the plural subject takes the verb stehen.

der Bildschirm — screen; monitor; display; screen ​

Der Bildschirm is the screen of a computer, television or similar device. Its plural is die Bildschirme and its genitive is des Bildschirms; do not confuse it with der Monitor, which is also common for a computer screen.
Der Bildschirm ist sehr hell.
The screen is very bright.
hell means bright. Der Bildschirm is nominative because it is the subject, and the finite verb ist stands in position two.
Ich sehe den Bildschirm nicht gut.
I cannot see the screen well.
sehen means to see, and nicht gut means not well. Den Bildschirm is accusative because sehen takes a direct object; the masculine article changes from der to den.
Sie sitzt vor dem Bildschirm.
She is sitting in front of the screen.
sitzen means to sit, and vor means in front of. Dem Bildschirm is dative because vor describes a fixed location here; movement towards the screen would require the accusative.
Die Helligkeit des Bildschirms ist zu niedrig.
The screen's brightness is too low.
die Helligkeit means brightness, and zu niedrig means too low. Des Bildschirms is genitive because it says whose brightness it is; the masculine noun adds -s in the genitive.
Die Bildschirme im Büro sind neu.
The screens in the office are new.
im Büro means in the office, and neu means new. Bildschirme is plural with -e, so the verb is sind rather than ist; im Büro is a fixed-location phrase with the dative.
Auf dem Bildschirm erscheint eine Nachricht.
A message appears on the screen.
erscheinen means to appear, and eine Nachricht is a message. Auf dem Bildschirm is dative because auf describes a fixed location; the verb erscheint is in position two and the new subject follows it.
Bitte tippen Sie auf den Bildschirm.
Please tap the screen.
bitte means please, and tippen means to tap. Auf den Bildschirm is accusative because tapping directs an action towards the screen; the formal command uses tippen Sie.

chatten — to chat online ​

Chatten is a regular weak verb borrowed from English and normally means exchanging written messages online. It takes haben in the perfect and commonly appears with mit plus the dative for the person you chat with.
Ich chatte jeden Abend mit meiner Schwester.
I chat with my sister every evening.
jeden Abend means every evening, and meine Schwester is my sister. The finite verb chatte is in position two; mit forces the dative, so meiner Schwester means “with my sister”.
Wir haben gestern lange gechattet.
We chatted for a long time yesterday.
gestern means yesterday, and lange means for a long time. The perfect uses haben plus gechattet; haben is in position two and the Partizip II goes to the end.
Früher chattete er jeden Tag mit Freunden.
He used to chat with friends every day.
früher means in the past, and Freunde are friends. Chattete is the weak-verb preterite in position two; mit Freunden is dative after mit.
Chatte nicht während des Unterrichts!
Do not chat during the lesson!
nicht means not, während means during, and der Unterricht is the lesson. Chatte is the du imperative and the subject is omitted; während takes the genitive here, so des Unterrichts means “during the lesson”.
Wenn ich mehr Zeit hätte, chattete ich öfter mit ihnen.
If I had more time, I would chat with them more often.
mehr Zeit means more time, öfter means more often, and ihnen means them. The sentence expresses an unreal condition; in careful German, würde chatten is more usual than using the preterite-looking form chattete, and the finite verb in the wenn clause goes to the end.
Morgen werde ich mit meiner Cousine chatten.
Tomorrow I will chat with my cousin.
morgen means tomorrow, and meine Cousine is my female cousin. Future uses werden in position two and the infinitive chatten at the end; mit meiner Cousine is dative after mit.

der Bildschirm is the screen and kaputt means broken. des Computers is genitive because it shows possession, and the noun adds -s after des.
