The English language is a weird, wonderful thing, influenced by and cobbled together from many other languages. Because of this, it includes many idiosyncrasies, like some words containing extra letters for no apparent reason.
For example, take the word, “scent”. It’s pronounced “sent”, but you could also spell that pronounciation “cent”… so either the “S” or the “C” is silent.
You are the Big Broadcast Judge & Jury… what’s your verdict? In the word “Scent”, is it the S or the C that’s silent?
