Vocabulary & Language

Linguistic patterns and usage statistics

The OI pattern frequently appears in scientific terminology, particularly medical words related to glands and conditions (thyroid, parathyroid). Many everyday OI words derive from the Latin root 'jung-' meaning to join or yoke, giving us JOIN, JOINT, and related terms. The pattern also marks words borrowed from Greek scientific vocabulary, where '-oid' means 'resembling' (ZYMOID, CYCLOID).

With an average length of 8.8 letters, OI words skew notably long compared to typical English vocabulary. Nouns dominate at 64%, largely driven by scientific and medical terminology that favors this pattern.

Middle English and French heavily shaped the OI vocabulary, often through parallel borrowing from Latin. The word POISON illustrates a classic migration path: Latin 'pōtiōnem' (a drink) became Old French 'poison' before entering English—the meaning shift from 'potion' to 'toxic substance' happened along the way. Greek contributions appear mainly in scientific coinages, where '-oid' became a productive suffix for 'resembling.'

BENZOIC stands out as a consistent performer across both games, but the real strategic divergence appears with J-words. JOIN scores 11 points in Scrabble but jumps to 14 in Words With Friends, where J is worth 10 instead of 8.
