To Grow Longer
To Be Stretched, To Make Progress, To Increase
intransitive verb, ichidan verb
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means stretch and the verb vocab version is to grow longer or to be stretched. It's often used figuratively, in which case you'll translate it as to make progress or to increase.
You know this is version where you aren't doing the stretching, it just kinda happens, because it's just like how your stomach stretches when you drink beer (びる). Its capacity just seems to increase so you can take in more and more beer.
The reading is the one you learned with the kanji, you lucky duck!
