I looked up this grammar point this morning, and just had to laugh at the example used.
(Appropriate description for the past six weeks or so?)
CONTINUOUS vs. CONTINUAL
The word continuous means unbroken, so that something that occurs continuously occurs with no breaks. The word continually describes something that occurs repeatedly over a period of time.
- At the end of the semester my phone rings continually as students try to exercise some sort of damage control over the disaster that they fear their grades are likely to be.
- It rained continuously for the first three days of our vacation.
