> Let’s try the opposite: “not left” is definitely something different from “right” - urrrgggh. “Do not go left” doesn’t mean to go right.
“maldekstra” doesn't actually mean “not right” — mal in Esperanto more precisely means “opposite.” Left is opposite of right, and so malmaldekstra (opposite of the opposite of right) is still right (dekstra).
“Not right” in Esperanto doesn't exactly mean left, either, just like in in English. That'd be ne + dekstra = nedesktra.
