This question is regarding when 幺 appears in traditional Chinese.
What is the simplified variant of 幺?
I asked this question on the cantodict forums recently, and one member gave this excellent response:
But it's still not clear to me what the answer is. I'm quite confused why so many online dictionaries seem to give 么 as the answer. Could it be that simplification in Cantonese is different to simplification in Mandarin?
I found over 20 words in ABC Comprehensive Chinese Dictionary where the traditional contained 幺 and the simplified form uses 么. This is a consistent mapping in that dictionary.
