Yes, I know og. My question was if in the context of a sentence like this, where beag refers to children, if it can mean "young", as it does in English, when one refers to "small children" or says to a child, "Maybe when you're bigger" where "bigger" means "older'.
In English the sentence "The boy is too small" can mean the boy is short, or that he's skinny, or that he's young. Are all such meanings inherent in the Irish sentence?
"beag" is lenited because of "ró".
But there are no implications for the feminine nouns, because "ró" is usually used with predicative adjectives, and predicative adjectives don't have to agree with the gender of the noun ("tá an bhean beag" - "the woman is small", but "Is bean bheag í" - "she is a small woman".
"Tá an buachaill róbheag", "Tá an bhean róbheag"
