Language techniques

The trees of the forest watched sympathetically over the lost child

What is the name of the technique that describes gory, gruesome events in vivid detail

The swishing sound of the swaying trees

It was the best day ever!

It was awfully good

When a word sounds like the noise being described

What is the name of the technique where a text contains vairous words that relate to the same theme

The sun was as large as a ball of butter

Time is a thief

A boiled egg every morning is hard to beat

The road was a ribbon of moonlight

The heartless teacher continued to ruthlessly set exam questions for the weary students

The old car awoke reluctantly from it's slumber, coughing a spluttering until it broke out into a loud road

The story leapt off the page
