Q:

Ways to Memorize "Discreet" and "Discrete"

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...) 

A:

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.

A:

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

A:

"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.)
