we
The German word 'wir' is the first-person plural personal pronoun, which means it is used to refer to a group of people that includes the speaker. It is the equivalent of the English word 'we'. It is important to note that German has three grammatical genders (masculine, feminine, and neuter) and the form of the verb changes depending on the gender and number of the subject. For example, 'wir spielen' means 'we play' and 'wir singen' means 'we sing'.
We did not do that.
The sentence 'Das haben wir nicht gemacht.' translates to 'We did not do that.' in English. Here, 'wir' is used as a subject pronoun in the sentence. The phrase is in the past tense, denoted by 'haben' and 'gemacht', meaning 'done'.
Can we have another ice cream?
The German question 'Können wir noch ein Eis haben?' means 'Can we have another ice cream?' in English. In this sentence, 'wir' is used as the subject of the sentence. The verb 'können' is a modal verb that shows ability or possibility, and 'noch ein Eis haben' signifies the act of having one more ice cream.
