I missed this one thinking "caislean" would be lenited "gcaislean" since it was preceded by "an". Can anyone shed some light?
Not unless there is a proposition : ag an gCaisleán = at the Castle
Would caislean not be lenited here, due to being preceded by "an". I thought I was getting the hang of it. Thanks!
caisleán is a masculine noun. Only feminine nouns are lenited after the singular definite article an.
