IPA: /ˌʌnəˈmeɪzd/
KK: /ʌnəˈmeɪzd/
Not feeling surprise or wonder; remaining indifferent or unimpressed.
She was unamazed by the magician's tricks, having seen them all before.
Unamazed → It is formed from "un-" (meaning not) and "amazed" (from Old French *esmaier*, meaning to stun or astonish). The word "unamazed" means not astonished or not stunned.
Think of 'not' ('un-') being added to 'astonished' — so unamazed means you are not astonished.
