I have my phone language set to French, to help me learn. I opened up my work app, which was previously set to English, and a prompt popped up asking if I’d like to change the app’s language to French. But instead of “changer en français,” it said “changer pour français.”
This seems to have the nuance of “exchange for” as in “switch,” rather than “change to.” Am I at all correct? If not, why the preposition “pour” and not “en”?
