Left
忄 is the heart radical in its left-side form —
心 squashed vertical with central stroke and two drop-marks for the chambers. Anchors
情 in the emotion family. The original sense was 'authentic feeling from the heart', from which came love, sentiment, and the social bonds we feel. Same family:
怕 fear,
怀 harbor,
慢 slow-hearted,
快 quick-hearted.
