Different pronunciations of 等


When 等 comes after a word, how can I know when to pronounce it as など or とう?

According to a colleague of mine, it's usually pronounced とう when read and など
when spoken.




など reading is
[kun'yomi](https://en.wikipedia.org/wiki/Kanji#Kun%27yomi_\(native_reading\))
(native Japanese in most cases, but there are few exceptions).

とう reading is [on'yomi](https://en.wikipedia.org/wiki/Kanji#On%27yomi_\(Sino-
Japanese_reading\)) (Sino-Japanese; borrowed from Middle Chinese to Old
Japanese or Middle Japanese).

When both kun'yomi and on'yomi readings are possible, on'yomi sounds more
formal / literary. (Compare how in English, words borrowed from Latin or
French often sound more formal / literary.)
