to contaminate
☣️ contaminar = con (with) + tamin (touch) — to touch with filth
From Latin contaminare, built on con- (together) and the root of tangere (to touch). Originally it meant mixing or touching something pure with something impure, which is why Spanish uses it for both pollution and corruption or profaning.
