Variant form of 戔

𭟯 is a rare variant of 戔, an old Han character with senses including “damage” and “small.” 戔 appears in oracle-bone inscriptions—early Chinese writing carved on bones or shells—and its ancestral shape is read as two crossed ancient weapons with side blades, a picture of harm. A classical phrase 戔戔 was also glossed as “clever speech”; 殘 later became the usual written form for damage.
