spoonerism \noun:

The transposition of usually initial sounds in a pair of words.

Some examples:

We all know what it is to have a half-warmed fish [“half-formed wish”] inside us.

The Lord is a shoving leopard [“loving shepherd”].

It is kisstomary to cuss [“customary to kiss”] the bride.

Is the bean dizzy [“dean busy”]?

When the boys come back from France, we’ll have the hags flung out [“flags hung out”]!

Let me sew you to your sheet [“show you to your seat”].

Spoonerism comes from the name of the Rev. William Archibald Spooner (1844-1930), a kindly but nervous Anglican clergyman and educationalist. All the above examples were committed by (or attributed to) him.

Very cute juliet. I will have to remember that one…talko’s

But my brother calls them “talko’s” (as opposed to “typos”).
