transitive verb, godan verb
If you consign something to someone, you are going to entrust them with that item. Here you go, I entrust you.
The reading for this one is unusual, but I will entrust you with the knowledge of why to help you remember it! This uses the on'yomi reading and not the kun'yomi, as you might expect, because the す here is the old-fashioned version of the verb する.
Luckily, you learned this reading when you learned the kanji, so it's unusual but hopefully not too hard!
It was a mistake to entrust all the pictures to that detective.
