The baby name Declan is a Male name , 2 syllables long and is pronounced /ˈdɛklən/; DEK-lən (DEK-lan).
Declan is Irish in Origin.
Declan is the anglicized form of the Irish given name Déaglán (also rendered Deaglan), likely from deagh “good, excellent” + lán “full,” giving the meaning “full of goodness”; a devotional gloss “man of prayer” is also associated. In English it’s pronounced DEK-lən; in Irish, roughly DAY-glawn.
It entered wider use through the cult of St. Declán of Ardmore, a 5th–6th‑century missionary in Munster, and persisted in regional and ecclesiastical circles. The name later waned, then revived in the late 20th century, rising sharply in Ireland and spreading to Britain, Australia, Canada, and the United States. Variants and spellings include Irish Déaglán (Deaglan) and modern respellings Decklan and Deklan; nicknames Dec and Deccy are heard. Today Declan balances deep Gaelic heritage with a brisk, contemporary sound.
