An English form of the Irish name Deaglán, the meaning is unclear, but according to some sources may possibly mean either “man of prayer” or “full of goodness.” So basically a compassionate and virtuous Irish dude. If that sounds like what you’re going for, it can’t hurt to name your son Declan.
Dec, like the outdoor platform you sit on.
Famous people named Declan:
