To Be Pickled
To Be Well Seasoned, To Be Submerged, To Be Soaked
intransitive verb, godan verb
You already learned that 漬ける means "to pickle," so this means "to be pickled."
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You learned this reading already when you learned 漬ける, so you should be able to read this one too.
