How do you read Mathematica?

Mathematics has a symbolic notation, but there has emerged a way to
read it. For instance we know what notation these phrases refer to:

x to the power of 3.
integral of f of x dx, from x equals a to b
sum of 1 over n squared, from n equals 1 to infinity

If you can read a notation in English, it facilitates communication
and your memory. Is there any proposal how to pronounce things in
Mathematica?

For instance

A /.x -> b   may be read as "A given that x goes to b".  Alternatively
"A given that x takes the value b". Alternatively "A where b is
substituted for x".

A/;B   may be read as A provided that B.

Sqrt /@ {1, 2, 3}   may be read as "Square root mapped inside
{1,2,3}". Alternatively 	"Square root mapped over {1,2,3}".

Plus@@{1,2,3}   may be read as "Plus applied to {1,2,3}".
Alternatively "Change the head of List[1,2,3] to Plus".
