“Interim” is one of those words that I keep forgetting how to spell.
(https://www.dictionary.com/browse/interim)
Here are the ways you don’t spell it (I’m including this list so I can Google search my name and incorrect spelling to find this post):
intirum
interum
intrum
intrem
intram
intarum
interum
Once against, the correct spelling is
Interim
A Memory Mnemonic
Here’s a way I thought of to remember how to spell it:
Think “In term” but with an “i” in term.
