Tips
usage
丨 is not a standalone word - it is the basic vertical stroke (竖) and a Kangxi indexing slot. You meet it as the spine of characters like 中, 旧, and 串 rather than as something you write or say on its own.
history
In modern Chinese it survives only as a stroke name and a dictionary header.
Radical
LineKangxi #2
The vertical-line radical. A pure structural slot for indexing characters whose dominant feature is a single downstroke piercing or anchoring the form (中, 申, 串). Not productive in modern coining but useful when looking up otherwise hard-to-classify shapes.
