A.T. Robertson Commentary 1 Corinthians 14:10

"There are, it may be, so many kinds of voices in the world, and no [kind] is without signification." — 1 Corinthians 14:10 (ASV)

It may be (ε τυχο). Condition of fourth class (ε and aorist optative of τυγχανω), if it should happen. Common enough idiom. Cf. τυχον in 16:6.

Without signification (αφωνον). Old adjective (α privative and φωνη). Without the faculty of speech (12:2; Acts 8:32; 2 Peter 2:16).
