About
The character "卡" structurally merges the components for "above" and "below" into a single graph, conceptually depicting something wedged or stuck between two levels, which originally conveyed meanings of obstruction, such as a blockade or a checkpoint. This foundational sense of being impeded gradually extended to include various forms of clamping or jamming, both in physical and abstract contexts. Over time, the character's utility expanded through phonetic borrowing to accommodate imported words like "card", layering this modern loan meaning onto its existing ideographic core without changing its written form.
