From my time of learning conjugation tables by heart, I seem to remember that there were a few verbs which had multiple, grammatically correct, ways of conjugating them into present perfect . However, googling a while did not reveal any, and I am starting to wonder whether my memory is simply betraying me. Any ideas?
As noted by some of the commenters (like @VictorBarzov & @S.Baggy) there are several:
- hung vs hanged <== special connotation
- dreamt vs dreamed
- got vs gotten
- drug vs dragged <== dialectic, use with caution
- lit vs lighted
Do be careful with hanged, as it has special connotation with a method of execution (hanging). Also, be careful with drug; popular consensus pegs it as a variant limited to a dialect of English, not the language as a whole. Worse still, the more common definition is pharmacological, so perhaps it's better to avoid this one in anything but the most informal of settings.
