deturpate
To defile; to disfigure.
obsolete, transitive
Such as that which is to be seen in Burchards, and such which are too largely described in Sanchez; which thing does not only deturpate all honest and modest conversation, but it teaches men to understand more sins then ever they knew of.
1664-1667, Jeremy Taylor, Dissuasive from Popery
Where it comes from
First attested in 1623; borrowed from Latin dēturpātus, perfect passive participle of dēturpō (“to defile”) (see -ate (verb-forming suffix)), from dē- + turpō (“to make ugly, defile”), from turpis (“ugly, foul”) + -ō.
