In personal names this element often combined with words meaning fair or bright. Over time Gaelic names shifted in spelling and pronunciation as Irish orthography developed and as names moved between Irish and English contexts.

In contemporary use Caoilainn has been revived and adapted by families looking for a name that feels authentic to Irish heritage while still working in wider English-speaking settings.
