capillar

Capillar is not an established standalone term in standard English; it is primarily encountered as a combining form capillar- derived from the Latin capillus meaning hair. It appears in scientific vocabularies to denote hair-like, slender, or thread-like characteristics. In many contexts, the direct English noun would be capillary, not capillar.

In biology and medicine, capillar- compounds describe structures or phenomena related to capillaries or capillary action, including hair-like vascular features or fine tubular channels. The most widely known concept is capillary action, the movement of liquids in narrow spaces due to adhesion and cohesion.

In linguistics, capillar- is treated as a productive combining form that forms adjectives and nouns indicating hair-like or slender form, depending on the language. Its exact usage can differ across technical fields and languages.

Capillar may also appear as a surname or branding in some contexts, but there is no major standalone topic by that name. For general reference, see capillary, capillarity, and related terms.
