after, since
Verb て form +
This grammar point is used to indicate that one action or event occurs after another, or that a state has continued since a specific action took place. It emphasizes the sequence of events.
Action after another action
Used to show that an action happens immediately or sequentially after another action is completed.
昼ご飯を食べ
I will go to the library after I eat lunch.
家に帰っ
Please wash your hands after you come home.
Since a point in time
Used to describe a state or period of time that has continued since a specific point in time or event.
この町に来
Ten years have passed since I came to this town.
運動を始め
I have been healthy since I started exercising.
When using this structure to mean 'since', the main clause usually describes a state that has continued up to the present. It differs from the simple 'after' meaning where the second action just follows the first in time.
