To Rescue
transitive verb, godan verb
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means rescue so the verb vocab version is to rescue.
すくう
The すく in the reading is a lot like the scue (すくう) part of to rescue, don't you think? Hopefully you do, so you can make the connection.
