From Old Irish cloisid, cloistid, apparently a conflation of coistid (“is silent, listens”) with clos (“hearing”). Coistid is a late form of con·túaisi, from Proto-Celtic *tauso- (“silent”) (compare Old Irish tóe (“silent”), Welsh taw (“be silent”)), from Proto-Indo-European *teh₂ws- (“still, silent”) (compare Sanskrit तूष्णीम् (tūṣṇīm, “silently”). Clos is related to clúas (“hearing, ear”), from Proto-Celtic *kloustā (“hearing, ear”) (compare Welsh clust), from Proto-Indo-European *ḱlewst- (compare Old English hlyst (“hearing”)), from Proto-Indo-European *ḱlew- (“to hear”).
- (Munster, parts of Connacht) to hear
