This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 歵 is uncertain. It combines 止 and 責, but the original semantic and phonetic roles are unclear.
Since the meaning is unclear, focus on the shape: 止 (stop) beside 責 (blame). Imagine stopping blame, but remember the meaning is uncertain.
For サク, imagine a sack (サク) being stopped from blame: sack -> サク, tied to the 止 and 責 components.
