Origin

The character 到 combines two parts: 至, which means "arrive" or "reach," provides the main meaning, and 刂 (a variant of the knife radical) on the right serves as a sound hint to suggest how the character should be pronounced. The left component 至 originally depicted something pointing straight ahead or moving directly forward, which naturally connects to the idea of reaching a destination. By pairing this meaningful component with the sound-indicating knife element, the character 到 came to represent the complete concept of arrival or reaching a goal. The sound component doesn't add meaning itself but helps readers know how to pronounce this particular character for the word meaning "reach."
