Paul condemns 'foolish talk' (μωρολογία) alongside coarse jesting in Ephesians 5:4 as out of place among the saints. The compound joins 'foolishness' (μωρός) and 'speech' (λόγος), denoting talk that is not merely trivial but morally vacuous—conversation that neither edifies nor honors God. In classical usage the term connotes babbling nonsense or speaking without understanding. Paul's vice lists often target sins of the tongue as much as sins of action, because speech both reveals and shapes the heart.
