Words, or maybe the tongue. I've heard of sharp-tongued people; ditto soft-tongued people, all based on the vocabulary and the way each person tends to present verbal information. In other words, you can be a sharp-tongued (sarcastic, belittling, demeaning, etc) or soft-tongued (affirming, positive, etc.)



There is an old, old illustration: I heard someone say that a certain woman could make time stand still. The speaker went on to say that the woman had a face that would stop a clock and observed that it's the same basic concept (!) but the verbiage was vastly different in terms of connotations, etc.What is sharper than a knife but softer than a cloud?
