What 蓽 means
A woven fence, gate, or screen. 蓽 carries the original fence meaning: a barrier of thorn branches or bamboo, with 篳 as its bamboo-radical relative.
The earliest attestation traced here comes from the Han dynasty 說文解字 tradition, glossing 篳 as a boundary fence and quoting the Spring and Autumn tradition. Later compounds carry the image forward: 蓽門 means a poor dwelling, while 蓽路藍縷 joins a brushwood cart and worn clothes into enduring hardship.
Literary and rare in casual chat; a lone 蓽 sounds like a classical quotation.
Use 蓽路藍縷 for hard beginnings, not 蓽 alone.
