Is the B silent in obvious?

Is the B silent in obvious?

Yes. The position of the “b” to the following “v” is vocally difficult to say. The sound you actually make is more a “p”.

Why do some words have a silent b?

WE OWE the silent 'b' to the fact that centuries ago our ancestors pronounced a b-sound: climb was Old English climban, and bomb comes from Italian bomba. The b-sound was lost by about 1300. It leaves traces to the present day, however, in pairs such as climb-clamber, crumb-crumble.

Is the B in BOMB silent?

The rule is simple: if a word ends in the letters mb, the b is silent. I already told you the word climb. Some others are thumb, comb, crumb, lamb, limb, bomb, and dumb.
