felmelegednek

Felmelegednek is a Hungarian verb form that appears as the third person plural present indicative of the verb felmelegedni. The base verb felmelegedni means to warm up or to become warm, and the prefix fel- conveys upward movement or completion. The form felmelegednek is used with plural subjects, such as people, objects, or natural phenomena, to indicate that they are warming up or becoming warmer.

In usage, felmelegedni is primarily intransitive: something becomes warmer rather than someone actively warming it. It can describe weather, air, water, and environments, as well as machines or spaces that increase in temperature when heated. The prefix fel- often emphasizes the onset or completion of the warming process. Related noun forms include felmelegedés (warming up) and felmelegítés (heating up or reheating).

Examples:

- A levegő felmelegedik a napon. (The air warms up in the sun.)

- A folyók felmelegednek az időjárás változásai miatt. (The rivers warm up due to changes in the weather.)

- A sütő felmelegedett, mire bementünk ételeket készíteni. (The oven had warmed up by the time we started cooking.)

Past tense forms include felmelegedtek (they warmed up) and felmelegedett (he/she/it warmed up). The present form felmelegednek is therefore used for plural subjects in the present, while other forms follow standard Hungarian conjugation patterns for -edni verbs.
