I don't know if I asked this question correctly, but what is a latin stem for swap? I don't specifically need it to be just swap. You can answer my question by saying a latin stm for switch, or another adj. for swap. Please, any of you, please get back to me as soon as you can. Thanks!
Depending on what you mean exactly I could envision constructions with transponere or some of the various verbs associated with commerce, like cambire (which is not Classical Latin but gave rise to English change).
