Gender agreement

In English, only pronouns referring to people show gender differentiation (the woman - she/her, the man - he/him). In German, pronouns referring to objects also show gender differentiation. Thus er / ihn / ihm are used to refer to masculine nouns, sie / sie / ihr to refer to feminine nouns, and es / es / ihm to refer to neuter nouns. All translate into English as "it."
