Tips

usage
㣺 is the laid-flat heart that occasionally sits at the bottom of a character to support a component above. Same semantic role as (feelings, will, thought) but rotated for layout. In modern type you'll usually see plain at the foot — 㣺 is mostly a dictionary header and calligraphy form.
history
When had to anchor a character from below, scribes flattened the four strokes wide instead of stacking them, producing this horizontal variant. Encoded as a separate codepoint for structural analysis, but most printed glyphs collapse back to when the radical sits at the bottom.
usage
Visible in classical or stylized renderings of (admire), (respectful), in older forms. For everyday reading, recognize at the bottom of (think), (miss/recite), (think), (angry) as the same heart radical in its standard bottom form.
