To Warm Up
To Get Warm
intransitive verb, godan verb
This word consists of kanji with hiragana attached. Because the hiragana ends in an う sound, you know this word is a verb. The kanji 温 means warm. So the verb 温まる means to warm up or to get warm.
温まる is intransitive, so no direct object needed. Your cat warms up in the sunlight, for example. No direct object, right? A hint for this is that 温まる ends with okurigana that rhyme with ある, and those kinds of verbs tend to be intransitive!
The kanji reading is the same as 温かい and 温める.
