Pronunciation: [ɐtˈakə] (IPA) 
The word "attacker" is spelled with a /k/ sound at the end, even though it is spelled with a "ck" instead of a "k". This is because the vowel sound before the /k/ is a short "a" sound, which is more typically followed by a "k" than a "c". The "ck" spelling is used to indicate that the preceding vowel sound is a short vowel, while a "k" after a vowel usually indicates a long vowel sound. So, the correct pronunciation is /əˈtækər/.

The word "attacker" originated from the Old French word "atakker", which came from the verb "ataquir" meaning "to attack" or "to assail". This Old French term was derived from the Latin word "attaccare", which meant "to join" or "to fasten". Ultimately, the Latin word came from the combination of the prefix "ad-" (meaning "to" or "towards") and the verb "taccare" (meaning "to fasten" or "to join"). Over time, the meaning of "attacker" evolved to describe someone who initiates aggression or assault.
