Phrases such as "wall in," "wall off," and "wall out" demonstrate the use of the word wall as a verb. I couldn't find a good translation for these phrases. I'm mostly wondering because I play a real-time strategy game that involves the use of defensive walls and players frequently say to each other "wall here" to mean "build a wall here," and I realized I wouldn't exactly know how that's said in French other than "faites un mur ici."
Literal translation of "wall in" should be "emmurer", which literally means "put someone/something in between 4 walls"
However, usage for this word has often to do with a state of mind, like "s'emmurer dans le silence" -> "refuse to reveal any information even if it causes complications and can't help"
Correct way of saying "build a wall here" is "construisez un mur ici" or "édifiez un mur ici" (last one is more formal). But playing a STR, I and most of my friends would just say "wall là", franglish.
