CJK Unified Ideograph-8E60

It means a sole, treading, jumping, or reaching.

Think foot first: the character combines 足, the foot field, with 庶 on the sound side. Classical sources use it for the sole of the foot and for foot actions — treading and jumping — alongside the extended sense of reaching.

Dictionaries also list 跖 as a variant, so do not treat every stroke difference as a different word. Copy it from the palette above when you need the exact 蹠 form.

Why is 蹠 read あしうら in Japanese?

In Japanese, it means the sole of the foot.

Japanese use centers on あしうら and あしのうら for the sole, while あなうら is the older, chiefly literary reading with an early example dated to 858. Later general usage favors あしのうら.

That sole image stretches into learned compounds: 蹠骨 is the metatarsal bone, and 対蹠 pictures soles facing each other to say opposite.

What if someone sends just 蹠?

Alone, it is not enough to read a sender's reaction.

There is no hidden emoji-style mood here. Ask which language and sentence it came from: classical Chinese foot language, a Japanese anatomical or abstract compound, or a Korean Hanja reference. Read it as text that needs context, not as a vibe.
