The grammatical term for commands is the imperative.
There are three forms of the command in German:
To form the 'du' command, use the 'du' form of the present tense of the verb, and remove the word 'du' and the '-st' ending:
| sprechen: du sprichst | Sprich nicht so laut! | Do not speak so loudly! |
| geben: du gibst | Gib mir das! | Give me that! |
Note that verbs whose stem ends in '-s' or '-ss' or '-ß' drop only the '-t':
| lesen: du liest | Lies das! | Read that! |
| essen: du ißt | Iß das nicht! | Do not eat that! |
Note also that irregular/strong verbs which add an Umlaut in the 'du' form do not keep the Umlaut in commands:
| schlafen: du schläfst | Schlaf nicht! | Do not sleep! |
| fahren: du fährst | Fahr nicht so schnell! | Don't drive so fast! |
To form the 'ihr' command, use the 'ihr' form of the present tense of the verb, and remove the word 'ihr', but keep the '-t' ending:
| schreiben: ihr schreibt | Schreibt euren Namen! | Write your names! |
| sprechen: ihr sprecht | Sprecht nicht so laut! | Don't speak so loudly! |
| geben: ihr gebt | Gebt mir das! | Give me that! |
To form the 'Sie' command, use the 'Sie' form of the present tense of the verb, and turn the two words around:
| schreiben: Sie schreiben | Schreiben Sie Ihren Namen! | Write your name(s)! |
Note that the verb 'to be' - 'sein' - is, as always, irregular:
| du bist | Sei ruhig! | Be quiet! |
| ihr seid | Seid ruhig! | Be quiet! |
| Sie sind | Seien Sie ruhig! | Be quiet! |
