Vocabulary & Language

Linguistic patterns and usage statistics

Most 13-letter words are nouns, reflecting how English extends base words through suffixes like -ification, -ization, and -ation to describe processes and states. The pattern also accommodates substantial adjective formation through -ical and -able endings. Adverbs ending in -ally round out the distribution, turning those adjectives into manner descriptions.

Latin dominates the etymology of 13-letter words, followed by Middle English and French contributions. This reflects how English technical and abstract vocabulary grew primarily through Romance language borrowings. The chain from CLAIRAUDIENCE—traveling through French, Middle French, Old French, and back to Latin clārus—illustrates how a single word can carry centuries of linguistic evolution.

OBJECTIVIZING tops both Scrabble and WWF, but the gap widens dramatically in WWF where J scores 10 points versus 8 in Scrabble. CIRCUMJACENCY climbs to second place in WWF thanks to this J bonus, despite not cracking the Scrabble top eight. Words with Z like ZIGZAGGEDNESS and ZINJANTHROPUS gain significant value in WWF where Z earns 10 points. If you're holding high-value tiles in WWF, prioritize words with multiple premium consonants.

Hidden Gems

Rare but valid words to surprise opponents

ACIDIFICATION

the process of becoming acid or being converted into an acid

AFFORESTATION

the conversion of bare or cultivated land into forest (originally for the purpose of hunting)

ALLEGORICALLY

in an allegorical manner

"the play ended allegorically"

AMBASSADORIAL

of or relating to or characteristic of ambassadors

AFFORESTATION means the conversion of bare or cultivated land into forest, originally for hunting purposes. This environmental term combines the prefix af- (toward) with forest plus the process suffix -ation. It's increasingly relevant in climate discussions and surprisingly valid in word games despite its specialized feel.
