IPA: /ˌʌn.dɪsˈmeɪd/
KK: /ʌnˈdɪsmeɪd/
Not feeling worried or afraid; remaining calm and hopeful in difficult situations.
She was undismayed by the challenges ahead and faced them with confidence.
Undismayed → It is formed from "un-" (meaning not) and "dismayed" (from Old French *desmaier*, meaning to lose courage or to dishearten). The word "undismayed" means not losing courage or remaining unshaken in the face of adversity.
Think of 'not' ('un-') losing courage ('dismayed') — that's why undismayed means to remain brave and unshaken.
