Is the word "Quay" even used in US English? https://en.wikipedia.org/wiki/Quay_(disambiguation) https://en.wikipedia.org/wiki/Quay_(disambiguation) gives quays all over the UK, Canada, New Zealand, Australia and Singapore, but none in the US -- with the exception of a couple of tiny landlocked towns in Oklahoma and New Mexico called "Quay". Are we allowed to call a mispronunciation a mispronunciation when it's only pronounced that way by people who have probably never encountered that word before?
