Etymology
亗 is an ancient variant form of 歳 (year, age). It combines 山 (mountain) and 二 (two), but the exact historical development is uncertain. The modern form likely arose as a simplified or calligraphic shorthand.
Meaning mnemonic
Picture a mountain 山 with two 二 harvest seasons stacked below it, marking the passing years and the aging of the land.
Reading mnemonic
For サイ, imagine a sigh of relief at the end of a long harvest year: sigh -> サイ, as the mountain watches over the completed cycle.
