Feszülni

Feszülni is a Hungarian verb meaning to tense up, to become taut, or to stretch tightly. It describes a change of state from slackness to tightness and is used for both concrete things—such as ropes or muscles—and for abstract states, such as nerves or atmosphere, where tension is felt or perceived.

In the physical sense, feszülni is used for things that can become taut. Examples: "A húrok feszülnek" (The strings are taut). "Az izmok feszülnek a gyakorlat közben" (The muscles tense during the exercise). Ropes, wires, and other flexible materials can likewise be described with this verb when they tighten under load or strain.

In figurative use, feszülni describes psychological or social tension. Examples: "Feszülnek az idegek a vizsga előtt" (The nerves are tense before the exam). "A beszélgetés feszültté vált" (The conversation became tense). The term is commonly employed to express emotional strain, anxiety, or a charged atmosphere.

Grammatical notes: feszülni is an intransitive verb that typically does not take a direct object. It conjugates like other Hungarian -ni verbs and can appear in various tenses and moods. Related nouns include feszítés (the act or state of tightening) and feszültség (tension or stress). The root fesz- conveys the sense of pulling tight or becoming taut, and its derivatives are widely used in everyday language, sports, engineering, and emotional description.
