I was thinking about 氡, radon recently. The pronunciation: dōng (dong1) seems to suggest that sound was borrowed from the ending of the English word. Wiktionary corroborates this theory:
Etymology
Borrowed from English radon.
This is quite interesting because most loanwords seem to come from the beginning of words, if anything, and especially not the middle or the end of a word. You might expect some form of: rui
, for instance, for radon.
What other loan words exist where the sound was borrowed from the middle/end of the original word?
