Etymology
Origin of arbitrarily
Explanation
Something said or done arbitrarily is done randomly or without much thought — like when you arbitrarily eat whatever happens to be on the buffet table at your cousin's wedding. The adverb arbitrarily describes something that's done haphazardly, based on random chance or on your own whim of the moment. If you go to a movie and know nothing about anything that's playing, you might arbitrarily choose one — based on the titles, the look of the posters, or on nothing at all. When there's not much reason behind your actions, they're done arbitrarily.
