A to Z OF SILENT LETTERS

In Spoken English, if a letter that should be silent in pronunciation is articulated, one might look stupid when s/he realizes the phonetical incorrectness of the pronunciation. 

A letter could be present in a written form, but absent in pronunciation. It means, a letter(s) could be boldly written and be muted in the pronunciation. A letter in a word could be silent, and an entire syllable could be silent in different words too. For instance, the T in DEPOT should not be pronounced; the S in ISLAND must be muted and the OR in COMFORTABLE could be silent. 

Many a time, letters might follow each other, but one will make a sound while another will be silent. It happens in PSYCHOLOGY (P is silent for S to make a sound), PHONOLOGY (P and H do not make their sounds, but the consonant sound /f/ replaced their sounds) etc. 

Thumb through the words with silent letter(s) under each letter of the English alphabet below:

R: Farmer, Guitar, Forefathers etc.

S: Island, Chassis, Isle, Debris, Bourgeois etc.

T: Debt, Apostle, Beret, Listen etc.

U: Guard, Build, Guess, Tongue, Laugh etc

V (The letter seems not to be silent words)

W: Who, Sword, Wrath Whole etc.

X: Faux etc

Y: Beyond (The letter is not completely silent. The articulation of it - depends on how a pronouncer pronounces it) It make be articulated as BE-OND without the sound /j/.

Z: Rendezvous Chez etc.

In short, letters that are known as silent letters should not be articulated in words. Although a letter might be silent in a word, then make a sound in another word. For instance, T is silent in LISTEN, and it must be enunciated in RETIRE - If it is mistaken as a letter to be silent in RETIRE, one might end up in the web of malapropism.
