whether ’tis nobler in the mind to doubly miss the point

A little incident in folk grammar, funny to me at least. I wrote a sentence containing

. . . which led to reconstructing in my mind . . .

because

. . . which led to mentally reconstructing . . .

seemed wrong: everyone knows you don’t put an adverb between to and a verb form! (You’ll note that to reconstructing is not an infinitive, so the ‘rule’ does not apply.)

When I became consciously aware of that confused subconscious reasoning, I changed it to the latter.

I wonder how many now-standard grammatical features we owe to such extensions of misunderstanding.
