32.49 · Understand · Lack of Capacity for Understanding
without understanding, senseless, foolish pertaining to a lack of capacity for insight and understanding Care must be exercised in the rendering of ἀσύνετος in MAT 15:16 and ROM 1:21, since a lack of capacity for understanding may result from mental deficiencies or from a lack of the proper use of mental capacity. It is, of course, this latter meaning which is involved in the use of ἀσύνετος in these contexts.
