What does unridged mean?
Unridged is an adjective meaning “having no ridges.” It describes a surface, object, or area that lacks raised lines, ridges, or other projections. The word is especially useful when the presence or absence of a ridge is important: an unridged panel may be deliberately smooth, while an unridged stretch of land has no noticeable elevated crest. Its prefix, un-, reverses the meaning of the related word ridge, just as in unrelated terms such as untied or unfinished. Unridged is not common in everyday speech, but it can be effective in precise descriptive writing, particularly in discussions of architecture, materials, terrain, or manufactured objects. In general usage, it conveys a neutral observation about shape or construction rather than suggesting that the smoothness is either desirable or undesirable.

Etymology of unridged
The form combines the English prefix un-, meaning “not” or “the reverse of,” with ridge, an English word recorded from Old English. The underlying element appears in related compounds such as ridgeline and ridgepole, which likewise refer to a raised line, crest, or supporting ridge. Over time, un- became productive in English as a way of forming negatives from nouns and adjectives, allowing it to be attached to ridge with the straightforward sense “without a ridge.”
How unridged is actually used
