To Dangle Something
To Dribble Something
transitive verb, godan verb
You learned that 垂れる means "to droop" or "to drip." Well, this is the transitive version of that, meaning it takes a direct object. This time, you're the one making something droop or drip, which is why this word means to dangle something or to dribble something. You can remember it's transitive because of the す ending, which you've seen with lots of transitive verbs by now.
垂らす describes when you dangle something or let something hang in a way which allows gravity to act on it, like hanging a line when fishing. It's also used to describe letting something drip — for example, a little kid letting mucus drip from their nose or a sleeping person dribbling drool out of their mouth.
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 with 垂れる, but here's a mnemonic just in case you forgot:
You're going to dangle something, but what? You're going to dangle a taco (た) in front of a hungry person. Kind of a jerk move, honestly. You'll also probably end up dribbling taco sauce all over their shirt, which will earn you double jerk points.
