Pattern Guide

Insights and recommendations for these words.

Words with AI in the middle blend high-frequency staples with some genuinely surprising specimens. Here's how to put them to work.

Vocabulary & Language

Linguistic patterns and usage statistics

The AI pattern often signals words borrowed from French, where this vowel combination appears naturally in words like 'plaid' and 'chain.' Many AI words derive from Latin roots that passed through French before reaching English, picking up this spelling along the way. You'll find AI particularly common in agent nouns ending in -AIN (captain, villain) and in words describing actions or states (-AINT, -AIL).

With 66% nouns and 20% adjectives, AI words skew heavily toward naming things rather than describing actions. The average length of 8.7 letters suggests this pattern favors more complex vocabulary over simple building blocks.

Middle English dominates this pattern, reflecting how French-influenced spellings became standard after the Norman Conquest. The journey of CHIEFTAIN illustrates this path beautifully: from Late Latin capitāneus through Old French chevetaine into Middle English cheveteyn, the word's spelling transformed while its meaning stayed anchored to leadership. French and Old French together contribute a significant share, reinforcing AI as a marker of Romance language influence.

JAIL demonstrates WWF's scoring quirks perfectly—J is worth 10 points in WWF versus 8 in Scrabble, making this simple four-letter word punch harder in WWF. BAIZING and ZEBRAIC tie at 22 points in WWF but score differently in Scrabble due to the Z differential. For maximum impact, look for Q-containing options like QUAICH (20 in Scrabble, slightly less dominant in WWF where Q drops from 10 to 10 but other letters shift).
