Continual vs Continuous: Which One Do You Need?
Continual means repeated with breaks. Continuous means unbroken.
Continual interruptions. A continuous line.
The test that settles it
Ask whether it ever stops. If there are gaps, it is continual. If there are none, it is continuous.
“___ complaints from neighbours” → they come and go, so continual.
“a ___ supply of water” → never stops, so continuous.
Continuous ends in us, and us stay together — no gaps.
Continual: repeated, with pauses
Happening again and again over a period. There are breaks between the occurrences, and the word often carries irritation.
Continual delays wore everyone down.
His continual questions slowed the meeting.
Continual rain through the spring.
Swap in repeated. If it works, continual.
Continuous: unbroken
Going on without interruption in time or space. It is the word for lines, flows and stretches.

The exception
Plenty of good writers use the two interchangeably, and dictionaries record the overlap. But the distinction is genuinely useful, and readers who know it will notice when it is ignored.
One place it always holds: grammar. The present continuous tense is never called continual.
Where people get it wrong
