Ways to Memorize "Discreet" and "Discrete" [closed]

I have a question about discreet and discrete. People tend to get these two words mixed up, and I would like to help them memorize these two words.

Discrete: unconnected; separate
Discreet: judicially reserved; prudent

(Definitions from Word Smart...)

discrete

The best way to remember the difference is that concrete and discrete end the same: -ete. Something which is discrete is pinned down, precise: concrete.

discreet

The other one is that clandestine spies and surreptitious lovers should always meet in a discreet location instead of on the street, choosing instead somewhere far from prying eyes and ears, perhaps even behind a sheet.

The two e's in discrete are separated (by a t) just like the difference between discrete categories

"You could think of the adjacent e’s in discreet discreetly sharing a secret: they couldn’t do this with a t in the way." (Source.)

This is understandably difficult, as the etymologies trace back to the same ancestor.

I didn't really comprehend the difference until I took calculus, where I first realized that discrete values had nothing to do with being discreet.

Perhaps you could explain that discrete is used in math and science, and have your students recognize it as a sight word. In contrast, discreet is used in relationships, and they will probably use it more often in writing.

Another contrast would be the opposites:

• discrete / continuous
• discreet / indiscreet (or foolish or inconsiderate)

I always remember it by looking at the e's (the part of the word where they differ). In discrete, the e's are separated by the t so the e's are discrete.
