What is the meaning of the name Fiach ?

The baby name Fiach is a Male name , 2 syllables long and is pronounced FEE-akh (approx. /ˈfiəx/; 'ch' like Scottish 'loch').

Fiach is Irish in Origin.

Fiach is an Irish Gaelic masculine name (approx. FEE-akh, final ch as in loch) from Old Irish Fíach, meaning “raven.” The bird’s association with foresight, battle craft, and poetic inspiration in Celtic tradition gives the name a subtly mythic cast. Though modern Irish also has the homograph fiach “debt,” that sense is unrelated to the given name.

It appears in early annals as Fíach and Fíachu, and later in the famous Wicklow chieftain Fiach mac Aodha Ó Broin (anglicized Feagh MacHugh O’Byrne) of the 16th century. Related forms include Fiacha, Fiachna/Fiachnae, and Fiachra - the last giving French Saint Fiacre; the affectionate diminutive Fiachán means “little raven.” Anglicized spellings are typically Feagh or, less often, Fiach. Usage today is uncommon but distinctly Irish, sometimes chosen to honor heritage or the surname Ó Fiaich, which derives from the same root.
