A few of these got past you, which puts you in enormous company, including plenty of people who write for a living. These pairs are hard precisely because both spellings look right and both pass every automated check. The good news is that each one has a story attached, and stories are far easier to keep than rules. Once you know a stationer sold books from a fixed stall, the second e stops being arbitrary and starts being obvious.
“I ran the one-letter-off word trap and came away with the stories behind the spellings.”Solid. You have the common pairs filed correctly and slipped only where the two words genuinely overlap in use. That is the fairest kind of mistake to make, because a few of these traps are not really errors so much as leftovers from centuries when both spellings meant roughly the same thing. Your instinct for reading the sentence before choosing is exactly the right one; it just needs one or two more anchors.
“Careful drafter on the word trap, caught only by the genuine overlaps.”Impressive control. You are separating pairs that regularly survive into print, which suggests you read for meaning rather than shape and check the sentence around the word instead of trusting the look of it. That is the actual skill in proofreading, and it is rarer than a good vocabulary. Keep an eye on the pairs where both members can serve as verbs, since those are the ones that ambush confident writers most often.
“Sharp proofreader: I separated the pairs that usually survive into print.”A near-perfect run through traps built to catch experienced writers. You know that both members of at least two of these pairs can act as verbs, which is the detail that undoes most people. You probably also know that being right about this is only occasionally useful and never worth mentioning at parties. Enjoy it anyway. Precision about small words is a quiet pleasure, and the language is richer for people who bother.
“Near-perfect on the word trap. Yes, I know what a complement is.”
