Pattern Guide

Insights and recommendations for these words.

The EF- pattern rewards players who learn its high-scoring double-F combinations and understand its Latin-rooted vocabulary.

Vocabulary & Language

Linguistic patterns and usage statistics

Nearly every EF- word traces back to the Latin prefix 'ex-' (out) combined with roots beginning in 'f,' which assimilated to create 'ef-.' This explains the characteristic double-F in words like EFFECT, EFFORT, and EFFACE. The pattern produces words about outward action: effluence flows out, effusion pours forth, and effacement removes from view.

The double-F makes EF- words consistently valuable, but EFFLUX deserves attention—it scores 19 points in Scrabble versus 21 in WWF due to the boosted X value. EFFEMINIZING tops both games at 30 and 34 points respectively. Short plays matter too: EFF delivers 9 points in both games for just three letters, making it an excellent dump play when stuck with awkward F tiles.
