Tips

usage
qiǎ is the older native reading and covers physical pinching/wedging: 卡住 (to get jammed — also pr. kǎzhù), 卡脖子 (to seize by the throat / choke off), 卡壳 (gun jams; speech falters). It also names anything that pinches a flow of people: 关卡 (checkpoint), 哨卡 (sentry post), 边卡 (border post) — plus small clamp-objects: 发卡 (hair clip), 卡子 (clip; clasp).
memory
The character visually fuses (up) on top of (down) sharing one stroke — perfect picture of something pinched, neither going up nor going down. That's the core qiǎ image: wedged, jammed, blocked.

Components

radical
divination; downward stroke
Bottom radical is also the silhouette of (down) without its top bar. The qiǎ reading takes the visual pun at face value: a 'down' beneath an 'up', sharing the middle stroke = jammed between. From physical wedging came the extended senses of checkpost (a place that pinches a road) and clip/clasp (a small thing that pinches).
semantic
shàng
up; above
Top half is (up) minus its bottom stroke. Combined with the below — itself the silhouette of (down) without its top bar — the character pictures something pinched between up and down. This is the original native qiǎ image: wedged, stuck, lodged.
