aear

sea

aear (ocean); pl. aeair. The shorter form aer (for N oer) is maybe best avoided since it can be confused with aer "holy", unless the latter is actually a lenited form of gaer. Forms with g-, representing an alternative concept of the word for ”sea”: gaear (i **aear) (ocean), pl. gaeair (i ngaeair = i ñaeair) (PM:363), also gaer (i **aer, no distinct pl. form except with article: i ngaer = i ñaer), but homophones of the latter mean "reddish, copper-coloured, ruddy" and also "dreadful, awful, fearful; holy".
