Which of the first two letters on the word 'scent' is silent?
- if 's' is silent, the word cent is pronounced like we pronounce 'scent'
- if the 'c' is silent, the word is still pronounced the same, right?
So, which one of the letters is silent?
The "c" is silent when preceded by an "s" followed by an 'e' or an 'i' at the beginning of a word.
Found this on a site which had rules on silent letters. Authenticity is not known, but it sounds correct.
"Sc" can be a digraph (two letters combined to make one sound) or a consonant blend (two letters combined that make two sounds). This is why you hear one sound with the "sc" in "science" or "sent," and you hear two sounds with the "sc" in "scare." I would argue that neither is silent; it's used as a consonant digraph to make one sound.
According to the Online Etymology Dictionary:
late 14c., sent "to find the scent of," from Old French sentir "to feel, smell, touch, taste; realize, perceive; make love to," from Latin sentire " to feel, perceive,sense, discern, hear, see" (see sense (n.)).
Originally a hunting term. The -c- appeared 17c., perhaps by influence of ascent, descent, etc., or by influence of science. This was a tendency in early Modern English, also in scythe and for a time threatening to make scite and scituate.
This implies that the "c" is silent as the word was originally "sent". The addition of the "c" was likely to normalize it with words such as "science"; however, in Anglo-Latin, "c" is pronounced as "s" before front vowels e, æ, œ, i, y (It's pronounced as "sh" when not initial, before semivowel i and e). This would imply that it's actually the "s" that is silent as a result of palatalization.
In a way, both answers are correct, but a silent "c" is a better answer due to the origin of the word.
As you can see here, here and here, the words sent, cent, and scent are pronounced in exactly the same way, namely as [sent]. Hence, you may regard the "s" or the "c" as being silent in the sense that it does not modify the pronunciation. However, if you leave out either "s" or "c", the other is of course not silent.
Edit: I just discovered a much older discussion of this question on ELU here.
If the S is silent and not the C then it would be pronounced, "kent" instead of cent. The reason why is that the C isn't silent if the S is silent. So the C is silent.
