búvó

Bývá is a Czech verb form that expresses habituality or tendency in the present. It is the third-person singular present form of the imperfective verb bývat, which itself is a frequentative variant of být (to be). The use of bývá signals that a state or action occurs regularly, usually or characteristically, rather than being a one-time event.

Grammatical role and nuance: Bývá belongs to the imperfective aspect and conveys repetition or typicality. It is commonly used with time expressions or situational context to describe what tends to happen. It contrasts with present forms of být used for definite states (such as je) and with past habitual forms like bývalo for ongoing states in the past.

Etymology and related forms: The root comes from the Czech verb být (to be) and the derivational suffix -vat attached to bý- to form bývat, which carries a frequentative meaning—“to be in the habit of.” Related forms include bývám (I often am), býváš (you often are), bývá (he/she/it often is), býváme, býváte, bývají.

Usage in language: Speakers use bývá to describe ordinary, expected, or typical situations. Examples: V létě bývá horko. (In summer it is usually hot.) V neděli bývá na náměstí klid. (On Sundays there is usually calm in the square.) Bývalo is used for past habitual states: Když byl malý, bývalo to jiné. (When he was small, it used to be different.)
