Ways to tell them apart:
Occasional implies something happens at irregular intervals but not frequently enough to be considered a regular pattern.
Intermittent suggests a regular stop-start pattern that may occur at consistent or irregular intervals.
If something is occasional, it might happen once in a while, but intermittent could happen frequently but with breaks.
Remember that occasional is often used for events or happenings that you dont expect to occur often, whereas intermittent' may imply an expectation of recurrence.
You might use occasional for surprise or rare events, while intermittent might describe a persistent issue with pauses, like an intermittent internet connection.
