Are these real words?

Yes. Each one is an entry in Princeton WordNet and in Wiktionary with the part of speech the card shows. Invented words, brand names and names from shows and games are left out.

How this list was compiled

The selection is our own pick of words chosen for their sound, and so is the wording of every meaning; nothing here is a ranking. All 300 words were checked by script on 2026-10-01 two ways: against Princeton WordNet 3.1 (the word is a lemma there with the part of speech on its card) and against its English Wiktionary entry, read through the API that day (https://en.wiktionary.org/w/api.php; the entry has an English section with that part of speech as a heading; each card's x.src is the entry). The same script compared each meaning with the WordNet glosses and the entry's definition lines: a meaning that shared no content word with either was rewritten or the word was dropped, and none repeats a dictionary line. The language on a card ('From Latin') is the first language the entry's Etymology section names as the source English borrowed or derived the word from, read from the entry's own etymology templates; inheritance from Middle or Old English is not printed, and a card whose entry documents no such language prints none. It is the nearest source the entry gives, not the oldest: zephyr came into English from Latin, and Latin had it from Greek. Left out: words missing from WordNet (kraken, selkie, taiga, cordillera and tachyon among the candidates), every word on the funny word list, any word whose entry labels a sense vulgar, derogatory or pejorative (jade, slate, pearl, banshee, juggernaut, dragon, gargoyle and cyclops went for that), and brand, show and game names. Some of these words are also names of products; they are listed as the ordinary words they are. WordNet 3.1 is used under the WordNet licence of Princeton University; Wiktionary text is under CC BY-SA 4.0 and none of it is quoted. Licence: own work
