quoting Izambri, Duke, the Findible League:

#72
"Express “in front of” with a prefix, “behind” with a suffix, and “within” with an infix."

Nice idea for me, I think.

Something like, a made-up word "prao" would function as either one of the three. It depends on where you place the word.

Examples:
(Note: table will be translated as "chaloy")
In front of the table -> Prao-chaloy
Behind the table -> Chaloy-prao
Within (or on) the table -> Cha-prao-loy
