Historical forms of the character 思
Shuowen Jiezi (compiled in Han)	Liushutong (compiled in Ming)
Small seal script	Transcribed ancient scripts

Original form was 恖 (OC *snɯ), considered by Shuowen to be a phono-semantic compound (形聲／形声, OC *snɯ, *snɯs) : phonetic 囟 (OC *snɯns) + semantic 心 (“heart”). It may also be a ideogrammic compound (會意／会意) : 囟 (“fontanel”) + 心 (“heart”).

囟 started to corrupt into the unrelated 田 as early as the silk script.
