I’ve noticed three other Dopers make similar substitutions just in the past day and a half, e.g.
Is ‘ascertain’ supposed to be ‘assertion’? Is there any way spelling auto-complete could have done this? (Note that the two words have the same number of letters and similar letters, though they don’t rhyme.) Yesterday a Doper wrote ‘meant’ when ‘mention’ was intended. These substitutions seem to be common — has nobody commented on them before?
I wrote ‘called’ when I meant ‘killed’ today, but caught it on Preview.
