ihr pl

1. you, ye (plural, familiar)

• This form is the plural of du, which is used chiefly towards people with whom one is privately acquainted (see there). One uses ihr towards a group of people if one would address every individual in that group with du. However, the plural ihr is somewhat less familiar than the singular du, meaning that it can sometimes be used in semi-formal situations where du towards an individual would not be appropriate. Learners should still, in any case of doubt, use Sie in order to be on the safe side.
• The form Ihr (capitalized in writing) was formerly the polite second-person form for both singular and plural (compare French vous and Early Modern English you) and was used instead of contemporary Sie. Such usage still survives dialectally in some areas, and is encountered in historical contexts (e.g. fiction taking place in the distant past), but is otherwise rarely heard in standard German.
• The genitive pronouns are very rare. They are used only in literary and formal style as a genitive object for certain adjectives, prepositions, or verbs which govern the genitive, such as entbehren and gedenken.
• In the late 18th century and in the first half of the 19th century, the genitive was also eurer instead of euer, e.g. ich erinnere mich eurer instead of ich erinnere mich euer.^{[1][2][3][4][5]}

In older language the genitive is also written ewer and the accusative and dative sometimes ewch.

From Old High German iru, iro.
