Comparative form of ashy; more ash-like, grayish, pale, or covered with ash than something else.
From ashy (made of or resembling ash) plus the comparative suffix -er, which forms the comparative degree of adjectives.
The comparative forms 'ashier' and 'ashiest' are rarely used in modern English because we typically say 'more ash-like' or 'grayer'—showing how some comparative forms fade away as languages evolve toward longer descriptive phrases.
