What are some examples of alliteragtion?

Answer 1

The word you're looking for is alliteration. There is no G in the middle of it.

Alliteration is simply the figurative device in which an author repeats an initial consonantal sound, usually for a particular effect. So-called tongue-twisters are examples of alliteration, but they aren't usually very poetic in their effect.

e.g. Peter Piper picked a peck of pickled peppers.

When the alliteration creates a secondary poetic effect, often onomatopoetic, then the alliteration is being used to its best effect.

e.g. the wind was whistling by the window

The repeated initial W sound creates something of the effect of the wind itself.
