인칭대명사

Personal pronouns replace a noun so you don't repeat it. Subject pronouns — I, you, he, she, it, we, they — do the action and come before the verb.

English needs a subject in almost every sentence. Where some languages drop it, English keeps it: say 'It is raining', not 'Is raining'.

Object pronouns — me, you, him, her, it, us, them — receive the action. They come after the verb or after a preposition (to, for, with).

Notice the pairs: I → me, he → him, she → her, we → us, they → them. 'You' and 'it' stay the same in both roles.

In a full sentence the subject pronoun does the action and the object pronoun receives it. Compare: 'She loves him' — 'she' acts, 'him' receives.

A common mistake is mixing the two. Say 'He and I went home' (both subjects), and 'between you and me' (both after a preposition).
