Teplejí

Teplejí is a Czech verbal form that translates roughly as "they warm" or "they heat." It represents the present indicative tense for the third person plural, built on the stem related to warmth (tepl-). In usage, teplejí describes heating actions carried out by multiple subjects, such as people, furnaces, or natural processes.

The form is part of the broader Czech system of present tense conjugation, where many verbs in the same class take an -í ending for the third person plural. The exact base verb that teplejí derives from can vary by context; common related verbs include teplit (to warm) and ohřívat/ohřát (to heat up). Teplejí therefore functions as a general, everyday expression for plural warming actions and appears in both spoken and written Czech, including technical discussions of heating, energy use, and climate-related topics.

Examples of usage are typically straightforward: Oni teplejí dům kotlem. (They heat the house with a boiler.) Teplejí vodu v nádrži. (They warm the water in the reservoir.) In translation, teplejí is commonly rendered as "they heat" or "they warm," depending on the specific context and verb chosen for the statement.

Notes on scope and variation: teplejí is primarily a grammatical form rather than a standalone lexical item. Its precise meaning depends on the accompanying verb and context. It is distinct from singular forms such as tepleje (he/she warms) and from terms for heat sources or energy concepts that may appear in related discussions.
