⭕️ Use after + phrase, and use later alone (at the end of a sentence or phrase).
▶️ I’ll call you later.
I’ll call you after I get home from work.
▶️ First he bought a new car. Two weeks later, he bought a new motorcycle.
He bought a new motorcycle two weeks after he bought a car.
You can say “later + time period” to refer to an unspecified time in the future,
which is still within the period, for example:
▶️ I’ll finish the project later this week.
▶️ We’ll go on vacation later this year.
Never end a sentence with “after.” Instead, you can use “afterwards”
▶️ “Did you go straight home after the baseball game?”
“No, we went out for drinks after.”
“No, we went out for drinks afterwards.”
