億
부수: 亻
획수: 15획
億 means ‘a hundred million’.

億 = 亻 + 意
X = semantic + phonetic
• 亻 depicts a side view of a person and conveys the meaning ‘safe’.
• 意 is used phonetically (discussed below).
Evolution:
億 = ’safe’ ➔ borrowed use ➔ ’100 million’
意 = 音 + 心
• 音 is a stylised divergence of its original form 言 (speech) — with 口 changed to 日 for distinction and 立 developing through distortion. It is not 立 above 日.
• 心 depicts a heart and means ‘heart’.
Scholars debate the role of 意 in 億. Some suggest 意 conveys the meaning ‘heart brimming full of thoughts and content’ and for this reason, the character was selected for its numerical loan usage.
Mnemonic
Imagine a guru 亻 talking endlessly 億 about the meaning of life as he speaks 音(言) from the heart 心.
