About
The character 擦 (cā) is a phono-semantic compound, with the hand radical 扌 (shǒu) indicating a manual action and the phonetic component 察 (chá) supplying the pronunciation. Though 察 normally means 'examine' or 'observe,' in this character it functions only as a phonetic cue. Its core sense covers the physical motions of rubbing, wiping, or erasing surfaces, for instance, cleaning a table with a cloth or striking a match against a rough edge to ignite it. It can also describe the light contact of two objects grazing or brushing past each other.
