Why Arthur's rhythm shapes the middle name
Arthur is two rolling syllables (AR-thur) ending on an "er". Two traps hide in that ending: middles opening on R run straight into it (Arthur Reid becomes "Arthu-reid"), and middles ending in "-er" rhyme with it (Arthur Parker sounds like a law firm). Crisp consonant openers of one or three syllables give the name its knightly stride: Arthur James, Arthur Sebastian.

Arthur name meaning and origin
Arthur's origin is honourably disputed — the leading theory ties it to the Celtic artos, "bear", with Roman family-name Artorius close behind — but its meaning in practice is King Arthur, fifteen centuries of legend attached free of charge. The name has ridden a spectacular revival, helped along by royal middle-name use across several generations. Art and Artie are the classic short forms; test them with the nickname predictor.
