The word “scent” comes from the French root and when it entered English, the spelling kept the “c”, even though we no longer pronounce it separatelyAnd give reason why would u choose that letter!!
I don't know what to say..And give reason why would u choose that letter!!

If we remove the 'C' and write just 'Sent', the pronunciation remains the same. If we remove the 'S' and write 'Cent' (as in the case of currency), the pronunciation remains the same. However, according to the rules of English grammar, since the original meaning comes from 'S', the 'C' is considered silent.And give reason why would u choose that letter!!
And give reason why would u choose that letter!!
After deep investigation… I have concluded that both S and C are innocent.And give reason why would u choose that letter!!
