IPA: /ʌnˈmeɪld/
KK: /ʌnˈmeɪld/
Describing something that has not been sent through the mail.
The letter remained unmailed on the table for weeks.
Unmailed → It is formed from "un-" (meaning not) and "mailed" (from Old English "malian", meaning to send or dispatch). The word "unmailed" means not sent or dispatched, particularly in the context of mail or letters.
Think of 'not' ('un-') sending something ('mailed') — that's why unmailed means something that hasn't been sent.
