IPA: /ˈsmaɪtə/
KK: /ˈsmaɪtər/
A person who strikes or hits someone or something with force.
The smiter delivered a powerful blow to the target.
Smiter is derived from the verb "smite" (from Old English "smitan", meaning to strike or hit) combined with the agent suffix "-er" (meaning one who). Therefore, a smiter is one who strikes or hits.
Think of someone who 'strikes' ('smitan') and remember that a 'smiter' is a person who strikes.
