The word "formidable" originates from Latin formidabilis, derived from formido (meaning "fear" or "dread"). The morpheme formid preserves this sense of fear, while -able (from Latin -abilis) indicates capability or tendency. Over time, the word evolved in French (formidable) and English to describe something that inspires awe or is challenging to confront, blending the ideas of fear and capability.
