What is the interpretation and the poetic devices of the this stanza, poem, Tia Chucha by Louis Rodriguez

  I secretly admired Tia Chucha.

She was always quick with a story,

another "Pepito" joke or a hand-written lyric

that she would produce regardless of the occasion.                         

She was a despot of desire,

      uncontainable as a splash of water

on a varnished table.

In Spanish, 'Tia' means 'aunt.' So, basically the stanza is about a nephew or niece praising their aunt. Despite the fact that the speaker refers to her as uncontainable and a despot of desire, a love and admiration of her is unmistakable. The speaker admired her for her character as she was, loving her stories and jokes. 

Step-by-step explanation

Poetic devices

Alliteration- repetition of consonant sound in a line. She was a depot of pleasure. 

Metaphor- using something or a word to describe something else-a direct comparison of one thing to another. 'She was a despot of desire.' The subject is compared to something else in order toelaborate on her character. 

Simile- indirect comparison of a person or a thing to another, using 'as' or 'like.' 'uncontainable as a splash of water on a varnished table.'

Onomatopoeia- the use of a word that imitates its actual sound. The word 'splash' in the line uncontainable as a splash of water is onomatopoeic because the word imitates the actual sound of a splash of water.
