take quick, short steps
躩 centers on moving with hurried, short steps: taking quick, mincing strides, often in a nervous or constrained manner.
躩 combines 足 (foot) with 矍, which likely contributes both sound and the idea of hurried, watchful movement. The exact historical development is uncertain.
The foot radical 足 on the left suggests movement, while the right side 矍 looks like a pair of watchful eyes (目) over a hand (又) and a bird (隹), as if someone is nervously glancing around while taking quick, short steps.
For キャク, imagine someone taking quick, short steps in a cramped attic (キャク sounds like 'kyak' in 'attic'). The hurried, mincing steps fit the cramped space.
