I need to translate a lot of terms in a IT-application like button labels:
Can anyone translate these or is there any site with a list of common terms for French?
The most common button labels that come to my mind would be the following:
Another label you might see quite often in French is "Valider", it has more or less the same usage than a "Confirm"/"Ok" button, just remember that it's not exactly meaning the same thing as "Validate" in English.
Change your browser or operating system into French for a while and find out the corresponding terms that way. It's easy with Chrome or a Mac.
Have a browse through the FR-ER translation projects on the crowdsourcing site Crowdin, which constantly deals with these terms.
