What Is Ad Infinitum Usage Meaning

Ad infinitum is a Latin adverb for to infinity. Much like the famous Buzz Lightyear line, it implies something happening to infinity and beyond! But unlike Mr. Lightyear’s space adventures, ad infinitum usually refers to repetitive, endless processes rather than some exciting, interstellar escapades. Bummer, right?

In English, it’s not commonly found in relaxed settings, but you might come across it in formal texts and such. Whatever the case, it’ll follow the verb it’s modifying.
