How to say it
/eɪs/
Number one, expert
/eɪs/
From the Latin as (a unit, a coin) via Old French, then the playing-card meaning ('the one'). English by extension means 'top expert.' Ace Ventura (Jim Carrey, 1994) and Ace of Base anchor different generations.
Ace comes from the Latin as (a small Roman coin, 'a unit'), through Old French as. By the medieval period it meant 'the one' on a die or playing card; by the 17th century it carried the figurative sense of 'expert' (an ace pilot, an ace mechanic). As a given name Ace is modern American: rare before the 2000s, then climbing. Ace Ventura: Pet Detective (Jim Carrey, 1994), Ace of Base (the Swedish pop group), and the WWE's Ace Steel each pull in different directions. It entered the US top 500 in 2018. Single syllable, no shorter form.
