足す To Add Something

Meaning

Primary

To Add Something

Word Type

transitive verb, godan verb

Explanation

Remember 足りる? That is "to be enough." How can you make something be enough? You keep adding things to the pile until you reach that point where there are enough! That's why this verb is to add something, because you keep adding things until you 足りる.

This verb is transitive, like most verbs ending in す, which is why you are adding something. It's not getting itself added all by itself. Maybe you add so much that someone tries to sue (す) you for that nasty pile of squirrels you keep outside.
