Use the adverb universally to emphasize that something is done — or felt, or believed — in every single case.
If your new haircut is universally loved, it means that everyone, everywhere — with no exceptions — is a fan of your super short bangs. You might also describe getting a filling at the dentist as universally disliked, or a brilliant sunny day as universally cheering after a week of rain. The root is Latin, the word universalis, "of or belonging to all," which in turn comes from universus, "whole or entire." When a feeling or belief belongs to everyone, everywhere, it is held universally.
