Translation:We play with the ball each evening.
beginner here. so "Imrímid le liathróid gach tráthnóna." is we play with A ball each evening? is that right? or is it "Imrímid leis liathróid gach tráthnóna?" its that article before the noun that gets me, in this case "leis" or with "it". Is it to refer to a thing or someone thats feminine or masculine then the noun after it describes what it is? another example is "is é Dathai mo chara." is the bit before the noun only used when talking about something or someone specifically?
le becomes leis before a definite article - an or na. This is just a spelling change, the meaning doesn't change: leis an liathróid - "with the ball".
There is a different leis, the prepositional pronoun, the combined form of the preposition le and the pronoun é - "with him/it". This leis never occurs immediately before a definite article.
