The most crispy; superlative form of 'crispy.'
Superlative of 'crispy' (crisp + '-y'), formed with '-est.' This shows how adjectives ending in '-y' take '-iest' for superlatives: happy → happiest, crispy → crispiest.
The '-iest' ending actually developed because older English speakers found '-est' hard to say after '-y' sounds, so 'crispy' + '-est' merged into 'crispiest'—a great example of how lazy mouths shape language evolution.
