Meaning & readings

idea, thought, conception, think

On’yomi ソウ、ソ
Kun’yomi おも.う

Origin

The character combines "heart" () at the bottom, which is the classifying radical for mental and emotional concepts, with a sound hint component () at the top that tells you roughly how to pronounce it. Since thinking and ideas happen in the heart-mind, the pairing makes sense: the heart radical grounds the character in the realm of thought and emotion, while the top component signals the pronunciation. Together they create a character that means "to think" or "an idea" — capturing how Japanese speakers conceptualized the mind's activity as something of the heart.
