I heard the term "nominal" pronounced by a native speaker of American English and I realised that it was different from the usual British pronunciation.
I checked in online dictionaries and I found that:
Nominal (from Oxford Dictionary)
- BrE /ˈnɒmɪnl/ ; NAmE /ˈnɑːmɪnl/
while nominal according to the Cambridge Dictionary:
- /ˈnɒmɪnəl/ both for British and American English.
Other online dictionaries also suggest only the British pronunciation.
What is the correct or most common way to pronounce "nominal" in American English?
