～込む（こむ）

About

The verb 込こむ ("to put into") can attach to a verb's stem form to form a compound verb. Usage of ～込こむ can be separated generally into two categories: verbs of movement, and non-movement verbs.

込む adds the nuance that a verb is done, thoroughly/deeply, or that an action goes "into" something else.

E.g. 走はしる "to run" + 込こむ = 走はしり込こむ "to run into (something)"

E.g. 飛とぶ "to fly; jump" + 込こむ = 飛とび込こむ "to jump/fly into (something)"

With verbs of movement, 込こむ can add the meaning of "in/into", or deepen said meaning if it already exists.

E.g. マイクはサウナから出でたあと、海うみに飛とび込こんだ。

"After Mike got out of the sauna, Mike jumped into the ocean."

E.g. タイムカプセルを、深ふかさ1メートルくらいのところに埋うめ込こんだ。

"We thoroughly buried the time capsule about a meter down."

込こむ can also be used with verbs that don't involve any motion at all. For these verbs, 込こむ usually indicates that something is done thoroughly, for a long time, or until a certain result is achieved.

E.g. 友達ともだちと話はなし込こんでいたら、終電しゅうでんがなくなってしまった。

"I got lost in conversation with my friend and missed the last train."

E.g. この作品さくひんは細部さいぶまで作つくり込こまれている。

"This work has been perfected down to the details."
