Somewhat resembling or containing gravel; having a slightly gravelly quality.
From gravel + -ish (suffix meaning somewhat or having the character of). The -ish suffix comes from Old English and creates approximate descriptors.
The -ish suffix is one of English's most playful tools for creating descriptions that mean 'kind of but not really'—like calling something 'gravelish' when you're not sure if it's actual gravel or just looks like it.
