For example:
* "His lateness was excusable due to the heavy traffic."
We can also use "apologetic" to describe someone who is expressing regret or making an excuse:
* "He was very apologetic for missing the meeting."
Finally, we can use "excusatory" to describe something that is intended to excuse or justify something:
* "Her excusatory remarks were not convincing."
These words are similar in meaning to "excuse" and can be used in place of an adjective form.
