adjective, accusative singular masculine (or instrumental singular, depending on context)
Analysis. Likely from a root meaning 'to swell' or 'to be prominent'; the -ika suffix forms adjectives. Used in contrast to sukkhuma ('subtle') in psychological and metaphysical contexts.
Etymology. Related to oḷa- 'swelling, bulge'; cognate with Sanskrit aulāra. The concrete image is of something thick, swollen, or prominent—hence metaphorically coarse or material in nature.
