mealy-mouthed

(mēˈlē-mouÞdˌ, -mouthtˌ)

adjectiveWord History: It seems fitting that Martin Luther, a man noted for the forthright expression of his ideas, may have had a hand in giving us the contemptuous term we apply to those unwilling to state facts or opinions directly. Mealy-mouthed may come from a saying such as German Mehl im Maule behalten, “to carry meal in the mouth, that is, not to be direct in speech,” which occurs in Luther's writings. In English we find the terms mealmouth (1546) and meal-mouthed (1576) recorded around the same time that we find mealymouthed (around 1572). Mealy-mouthed is the only form that survived to describe this trait described by Luther, which not only survives but flourishes in our time.
