Spelling matters

Is it aldehyde or alderhyde? How the hell I go through 2 years of chemistry in secondary school and then another 2 so far now in college, AND STILL SPELL IT WRONG?

Conjugal Visit

In the United States, a conjugal visit is a scheduled visit during which an inmate of a penal institutionsexual intercourse
with a visitor in a closely controlled setting. It is generally
stipulated that this visitor be a spouse. The generally recognized
basis for permitting such a visit is that, even though the inmate has
lost their rights with incarceration, their spouse still has the right
to enjoy sexual intimacy, and should not be required to divorce or commit adultery in order to enjoy conjugal rights.

OK, very enriching and comforting. Link.
