N is the negating letter at this length. NON- opens 147 of the 248 words and NEURO- adds 24, leaving 77 entries for every other N root. Only notwithstanding counts as everyday English, and the group averages 21.8 points.
What the N words are built from
- NON- opens 147 of the 248 words, and 60 of those end in S.
- NEURO- adds 24 more, from neuroscientists to neurofibrillary.
- 36 entries hold a Z, and nebuchadnezzars packs two of them.
- 122 close on S, 35 on Y and 21 each on E and L.
- Only notwithstanding belongs to common English.
- Scores run from 15 at the bottom to 41 at the top.
Why NON- controls this list
English negates with NON-, and a fifteen-letter word has room for it. nongovernmental, noncommissioned, nonprescription and nonprofessional are the recognisable ones among the 147.
The science cluster sits in NEURO-, 24 words deep. neuropsychology, neuroplasticity, neurobiological and neuroprotective are typical, and none of them turns up in ordinary conversation.
Suffixes that dominate other long word lists barely show here. Just 9 of the 248 end in -tion, and 6 of those are NON- compounds such as nonintervention and nonexploitation, so this list stacks prefixes rather than building derivations.
Which 15-letter N word scores highest?
nebuchadnezzars at 41, the only entry here above 34. Its two Z tiles are worth 20 points on their own, and the plural ending adds nothing to that total.
nephrectomizing follows at 34. Then five entries tie at 31: neurohypophyses, neurohypophysis, noncomputerized, nonobjectivisms and nonpartizanship.
The average is 21.8, and only 150 of the 248 carry a definition. This is a specialist list, better for a themed play than for quick points.
Two word lists that nearly agree
Collins carries 208 of the 248 words and NWL2023 203, and the two overlap on 167 entries. Only 41 words stay Collins-only, so most of the list survives North American play.
