encima
/enˈθima/ · A2 · prep
on top of, above
🔝 encima = en + cima: on the summit, so on top of
Cima means peak or summit, from Latin cyma (a sprout, the topmost shoot). Put en (on) in front and you get on the peak, which Spanish stretched to on top of anything. English cyme, a flower cluster, is a cousin.
