Decent, Descent, Dissent

I thought this might be a good one for today since Tuesday is election day here in the US. Two homophones, and a third word thrown in for good measure. While "decent" isn't pronounced the same as the other two, it is easily confused on the page. So I thought it was a good idea to include it here.

Decent (DEE-sent) – good, kind, caring
Descent (di-SENT) – moving downward
Dissent (di-SENT) – protest

Conscience & Conscious

Not precisely homophones, I still hear these words used in each other's place in conversation and see them switched from time to time in such literary masterpieces as blog posts, status updates, and user comments. I can understand why – they're tricky to spell, similar in meaning, and also similar in pronunciation. But they're not interchangeable.
Conscience [kon-shence] – (n.) your personal set of morals.
Conscious [kon-shuss] – (adj.) awake, aware, not asleep.

Altar & Alter

With an A – (n.) a table or platform used for religious ceremonies and sacrifices.
With an E – (v.) to make something different than it was.

Frankly, though, I hope this doesn't come off like I'm advocating for either side. Maybe I should go back to Olympic themed posts. :)
