Was it something I said or just the shows I watch? ;)
Soap box time.
No American TV viewers, when Ichabod Crane pronounces “Lieutenant” as “Leftenant” he’s not ” saying it wrong”.
The British were using that pronunciation long before the USA came to be and those of us in the Commonwealth as well as the British still use that pronunciation.
So if you want to be pedantic about it, YOU say it wrong.
But I won’t be that arrogant unlike some American TV viewers. I’ll just say you pronounce it differently. ;)
