formidable

The word formidable describes someone or something that inspires respect and even fear because of its power, size, strength, or difficulty. It is more than just "strong" or "difficult"; it suggests an obstacle that demands serious attention and effort to overcome.

Originally, formidable meant "causing fear." Think of a formidable army marching toward battle. While it still carries that sense of intimidation, today it is often used to describe something impressive in its strength or scale. A formidable athlete might dominate their sport, while a formidable challenge could test your limits.

You can use formidable to describe people ("She was a formidable lawyer"), places ("The Himalayas are a formidable mountain range"), or tasks ("Learning a new language is a formidable undertaking"). It's often used in contexts where there's an element of struggle or competition. A detective might face a "formidable suspect" who is clever and evasive, or a company might launch a "formidable campaign" to win market share.

Unlike simply being "hard," something formidable has a quality that commands respect, even if you are the one trying to defeat it. It is a word that acknowledges both power and potential difficulty, hinting at a challenge worth facing, or perhaps cautiously avoiding.
