IPA: /ʌnˈflæpəbli/
KK: /ʌnˈflæpəbli/
In a way that shows calmness and composure, especially in difficult situations.
She handled the crisis unflappably, keeping everyone calm and focused.
Unflappably → It is formed from the prefix "un-" (meaning not) and the root "flappable" (from the verb "flap" meaning to move or wave quickly, with the suffix "-able" indicating capability). The word "unflappably" means not capable of being flapped or disturbed, indicating a calm and composed demeanor.
Think of someone who is 'not' ('un-') easily 'disturbed' or 'shaken' ('flappable') — that's why unflappably means remaining calm under pressure.
