IPA: /ˌʌnəbˈdʒɛkʃənəbl/
KK: /ʌnəbˈdʒɛkʃənəbl/
Something that does not cause any objections or complaints; it is considered acceptable or agreeable.
The proposal was deemed unobjectionable by all members of the committee.
Unobjectionable → It is formed from "un-" (meaning not), "objection" (from Latin "obiectio", meaning a throwing against or opposition), and "-able" (meaning capable of). The word means not capable of being opposed or objected to.
Think of 'not' ('un-') being combined with 'opposition' ('objection') and 'capable of' ('-able') — this helps you remember that unobjectionable means something that cannot be opposed.
