Notes

GENERAL INFO

Son is a possessive adjective meaning "his," "her," or "its." It always precedes a masculine singular noun. There is also a masculine noun, *un son*, meaning "a sound."

USAGE

Son agrees with the *thing possessed*, not the possessor. For example, "Il a son livre" (He has *his* book) and "Elle a son livre" (She has *her* book). Both use "son" because "livre" is masculine singular.

TRAPS

Do not confuse "son" (masculine singular) with "sa" (feminine singular) or "ses" (plural). Also, remember the homograph *le son* (the sound/bran).
