Origin

This character combines water (the three-stroke water radical on the left) with the component 主, which serves as a sound hint—it tells you roughly how to pronounce the character. The water radical shows the character relates to liquids and flowing. The core meaning "pour" or "irrigate" comes directly from the visual idea of water, while the sound component 主 (pronounced "shu") guides the pronunciation toward チュウ. Over time, the meaning expanded to include related concepts like "flow into," "concentrate on," and even "notes" or "annotations" (where meaning "pours into" a text). The character's shape essentially pictures water doing something active—pouring, flowing, or directing.
