Today, I will cover the usage of “~te kimasu” which means “Going out to do something and come back”

Example
Go out from home – Uchi o (deru)demasu.
Buy bread – Pan o kaimasu.
Go home – Uchi ni kaerimasu.
Combination : Pan o katte kimasu (I go out to buy bread back)
Meaning : Pan (Bread), Deru (Go out)

In english, we do not use this kind of phrase but in Japanese, whenever they are do “something and come back”, ~te kimasu is used.

Other Examples
