L is also silent in could, should, would, as well as in calf and half, and in chalk, talk, walk, and for many people in calm, palm, and psalm.
We find it in lots of different words, and they are generally very common words. Many students try to pronounce these Ls, but in all these words, the L is completely silent. In walk, chalk, and talk, the L comes after an A, and the vowel is pronounced like a short O.

So why is it so hard to say the 'L' in words in English such as 'ball', when you already have this sound in your language as well? The reason is because there are differences in how we pronounce the 'L' sound in English. There are actually two different 'L' sounds in English called the light 'L' and the dark 'L'.

The word comes ultimately from the Latin salmon, but we got it by way of French, as we did with so many other food words. The French, as was their wont, had swallowed up the Latin L in their pronunciation, so by the time we English borrowed the word, it was saumon, no L in the spelling and so no L in the pronunciation.
