These are not among our seventh grade commonly confused words, but they are worth knowing.
CONTINUAL
vs CONTINUOUS? The first implies a steady duration over time, like
having your mail delivered every day at 2:00 "continually for 20 years."
Continuous indicates an unbroken, uninterrupted duration, such as a
thin stream of water coming out of your faucet 24/7 for a period of time
"running continously."
