What does "persay"/"per say" mean? [closed]
You heard:
It shouldn't break any of your site per se.
per se is a Latin phrase often used in English. It means "in itself". So the person who said per se could have meant: "It shouldn't break the site, but it could break other things that you care about." or perhaps "It shouldn't break the site, but it could cause problems that are similar to a broken site."
