What does the word le mean in English?
'le' is a definite, singular, masculine article meaning 'the' ; it is to be followed by a singular, masculine noun.
It would help if you told the name of the language that the word is from. In Spanish, le is "he" or "she" or "you" when added to the end of a verb, such as "Quiero decirle algo," means "I want to tell him (or her, or you) something." In French, le can mean the, him, her, it, or them.
