úhlem

úhlem is the instrumental singular form of the Czech noun úhel, which means angle or corner. In standard Czech, úhlem is used in contexts where an action, measurement, or description relates to an angle or orientation, such as in geometry, surveying, or technical instruction. It can also appear in figurative uses that describe perspective or approach.

Etymology and form: The word úhlem is derived from the noun úhel and is formed by adding the instrumental suffix -em, reflecting its function after prepositions or verbs that govern the instrumental case. This morphological pattern is a common feature of Czech noun inflection, allowing úhlem to denote “by angle,” “with an angle,” or “at an angle” in appropriate constructions.

Usage: In practical Czech, úhlem is most often encountered in technical or mathematical descriptions. It commonly follows prepositions that require the instrumental case, for example under or with a specified angle. A typical example is pod úhlem 30 stupňů, meaning “at an angle of 30 degrees,” used to describe orientation, cutting angles, or directional measurements. The form is also used when speaking about an angle as a parameter or constraint in design, construction, or geometry.
