Etymology
再 is thought to represent a repeated action, possibly derived from a pictograph of a fish trap or a structure used again. The exact historical origin is uncertain, but the meaning of repetition is well established.
Meaning mnemonic
The top stroke 一 and the lower shape 冉 together look like a structure being built a second time: 再 means again or twice.
Reading mnemonic
For サイ, imagine a sigh of repetition: you sigh (サイ) when you have to do something again. The sound of a sigh cues サイ while the kanji means again.
