borrow, rent
借 centers on obtaining something temporarily from another: borrowing or renting. The idea is always about using something that belongs to someone else for a limited time.
借 combines 亻 (person) with 昔, which likely contributes the sound and carries the idea of something past or temporary, fitting the sense of borrowing.
A person 亻 beside 昔 (old times) suggests using something from the past temporarily. Imagine borrowing an old tool from a neighbor just for one job.
For シャク, imagine borrowing a shack for a weekend getaway: shack -> シャク, and the person 亻 is temporarily using the old 昔 building.
