I often come across word confusions when I'm beta-reading or reviewing books (including books from major publishers, by the way).
This page offers a list of easily confused words for authors, all of which I've seen in published books. If you want to be updated when I add new entries, please subscribe in the right-hand sidebar.
If you have additional suggestions, please leave a comment. Obviously, this isn't comprehensive, which is why your best plan is always to check all your vocabulary words before you publish.
(My book The Well-Presented Manuscript includes a much longer list, over 100 entries, categorised by how frequently I see them.)

adopt means to take on (a practice, etc.).

effect is usually a noun: The effect of raising interest rates is that fewer people borrow money.
However, there is a noun "affect" (pronounced with the emphasis on the second syllable instead of the first, AF-fect) which is used in psychology to mean "the ability to feel things": He suffered from flat affect.

The safest thing with this pair is to check every time.

There's a simple test for this pair. "Indiscreet" is the opposite of "discreet", and will be in your spellcheck dictionary, but there's no such word as "indiscrete". Put an "in" on the front, and if spellcheck queries it, you have the one that means "separate".

No pair is confused more often than it's and its (and the similar pairs they're/their and who's/whose). This is probably because English usually uses an apostrophe to indicate possession (the boy's book), but in these pairs the rule is the other way around:
it's is an abbreviation for "it is".
its means "belonging to it".
The easiest way to remember this is that it forms a consistent pattern with other pronouns and abbreviations:
he's, she's, it's, they're, we're, who's are all abbreviations.
his, hers, its, their, our, whose are all possessives.
So, if in doubt, ask, "Can I substitute 'he's' or 'his' for this word?" Then use an apostrophe if the answer is "he's" and don't use one if the answer is "his".

The phrase may be indicates that something is possible: "That may be the biggest dog I ever saw." You could substitute "could be", "might be" or "has to be" and the sentence would still make sense.
