Chinese character 蟰

It appears in 蟰蛸, a classical name for a small, long-legged spider.

《說文解字》 is an early Chinese dictionary. Its entry defines 蟰蛸 as a kind of long-legged spider, preserving 蟰 inside an animal name.

The pairing is a fixed animal name, not a freely assembled sequence.

Is 蟰 the same as 蠨?

蟰 and 蠨 are variant spellings in the same spider name.

蟰蛸 and 蠨蛸 are both recorded for the spider; 蛸 is the second character in each term. Dictionaries also give 蟢子 and the names 喜子, 喜母, and 喜蛛 for the creature.

Historical Chinese sources record a folk belief that a spider appearing on clothing or at a doorway foretold a guest or good news. The omen belongs to the animal tradition, not to every message containing 蟰.

What does 蟰 mean when someone sends it?

Alone, treat it as the character or a literary reference.

If it arrives alone, ask the sender what they mean instead of assuming “spider” or “good luck.” In a dictionary discussion, quotation, or character list, the exact written form may be the point.
