Podtrhne

Podtrhne is a form of the Czech verb podtrhnout, meaning to underline or underline text, and to highlight for emphasis. It is the third person singular present indicative form, and because podtrhnout is a perfective verb, the present form often conveys a future action rather than a continuous, ongoing one. In practical use, sentences such as “On podtrhne text” can be interpreted as “He will underline the text.”

In editing and typography, podtrhnout refers to adding a horizontal line beneath characters. Historically, underlining served as a primary method of emphasis in manuscripts and early print; in contemporary writing it is less common for emphasis, with italics or bold styles being preferred. Underlining remains encountered in specific contexts, such as certain forms of handwritten text, some teaching materials, or in web content where it may indicate a hyperlink, though this usage is more associated with interface conventions than with standard emphasis in Czech typography.

Related forms include the noun podtržení, which denotes the act or result of underlining, and the verb podtrhávání, describing the ongoing or repetitive process of underlining. The verb also has imperfective counterparts in Czech, used to describe habitual or repeated underlining actions, though podtrhnout itself is commonly used for single, completed actions.

Etymology traces the word to prefix pod- meaning “under” and trhnout meaning “to pull,” creating a sense of drawing a line under something. See also related terms such as podtržení and podtrhávání for broader discussion of emphasis techniques in Czech typography.
