Oblíqua

Oblíqua is the feminine form of the Latin adjective obliquus, meaning slanting, oblique, or indirect. In Latin and in languages that borrow from it, oblíqua agrees with feminine nouns to express obliqueness. The root obliquus appears in many technical terms, and the English cognate oblique reflects the same sense of slanted orientation.

In geometry and related disciplines, oblíqua describes lines, planes, or directions that are slanted relative to a reference. An oblique line, for instance, is one that is not parallel to a given line and does not form a right angle with it; the term conveys deviations from a standard orientation.

In anatomy, the adjective appears in the names of muscles and other structures. The external and internal oblique abdominal muscles are commonly cited as musculi obliqui externus and internus abdominis. In Latin and Romance-language technical usage, oblíqua may modify feminine nouns to denote obliqueness in various anatomical terms.

In botany and other fields employing Latin descriptions, oblíqua can describe oblique features of leaves, petals, or stems when the describing noun is feminine. The term is part of the broader Latin-based vocabulary that communicates orientation and angle in scientific descriptions.

Overall, oblíqua is a grammatical form used predominantly in Latin and in technical vocabulary derived from Latin to indicate slanted or non‑perpendicular orientation. It appears across disciplines that describe spatial relationships, including geometry, anatomy, and botany, where feminine noun agreement governs its use.
