'''Ceitleann Chraos-Fhiaclach''' is the slightly different form of the nickname that occurs in the Fenian cycle story {{illm|Bruidhean Chaorthainn{{!}}''Bruidhean Chaorthainn''|ie|Bruidhean Chaorthainn}}<ref name=pearse/> ("The Fairy Palace of the Quicken Trees",<ref name=joyce-pw-quicken/> "Rowan Tree Palace",<ref name=pearse/> "The Story of the Rowan Tree Dwelling"<ref name=leabhar-na-feinne-v1-p086/>). The headword, ''craos'' ({{langx|sga|cráes}}) can mean a 'gap, gaping, yawning', as well as 'voraciousness',<ref name=odonaill-craos/><ref name=dil-craes/> but Pearse has accepted the latter sense, and glosses the name as "ravening tooth".<ref name=pearse/> This '''Ceaithlann ''' also appears in Scottish copies of this tale.<ref name=leabhar-na-feinne-v1-p086/>
