Question

What is the following key word used for?

Answer 1

Idk but id say sequence??

Answer 2

Time

Time is correct because it shows when something is done. It doesn't show however, the exact sequence. For example, I brushed my teeth later in the day. This doesn't tell if it happened before or after eating lunch, getting dressed, or running a mile. If someone says they will call you later, you don't have an exact idea of their sequence of events, but you do have an idea of the timing.
