So I'm watching an old episode Law & Order and they start talking about a Lexus luxury car. Briscoe 'guesses' the car is black. I think to myself "Weren't they originally made only in black? ...no, wait, I seem to recall first-gen silver Lex... Lex... Lexuses? Lexii?" And my brain promptly crashed.
Friends, Romans, countrymen - but especially English majors and other cunning linguists - what, pray, is the plural of 'Lexus'?
