Is the L in calm silent?
The answer is the year 1066 and 2000 years of invasions, occupations, and political complexities that go far beyond “correctness.” “Calm” does, in fact, have a silent L because of 1066; however, in some regions it has a lightly pronounced L. Why? Because that’s how language works naturally over time.
