Question

"He stalks in his vivid stripes
The few steps of his cage,
On pads of velvet quiet,
In his quiet rage."
Which poetic device is used in the last line and where?

Answer 1

In the line In his quiet rage, quiet rage is an oxymoron.

An oxymoron is a figure of speech in which apparently contradictory terms appear in conjunction.

Here 'quiet' and 'rage' are two opposite words combined together to show that the tiger wants to roar in his rage but keeps quiet instead.
