Etymology: "Unconvincible" is simply the English prefix "un-", meaning "not", attached to "convincible", which means capable of being convinced. Convincible itself is formed from "convince" plus the adjective-forming suffix "-ible", so the whole word reads literally as "not able to be convinced" and has the sense of being fixed beyond persuasion. The base word "convince" comes from the Latin "convincere", meaning to overcome thoroughly or to prove conclusively, built from "com-" (together, thoroughly) and "vincere" (to conquer). That origin is worth remembering, because the word once carried the sense of defeating an opponent in argument rather than gently winning them over. "Unconvincible" inherits the same logic: someone who is unconvincible cannot be overcome by reasons.
