Two-syllable Greek words built around a specific double-consonant cluster are catalogued letter by letter — Β, Γ, Δ, Θ, Κ, Μ, Π, Σ, Τ, Φ, and Χ — with each letter's list split between words where the cluster opens the word (ΑΡΧΙΚΗ ΘΕΣΗ) and words where it falls in the middle or end (ΤΕΛΙΚΗ ΘΕΣΗ). Most entries pair the target word with its own letters presented out of order, turning the list into an anagram exercise: students read the intact word, then reconstruct the scrambled version back into the same spelling. The twenty-one-page set moves through eleven consonant-cluster letters this way, one after another.
