parallelism
Answer:
parallelism
Explanation:
Parallelism refers to the use of similar grammatical structure among sentences in a text, so that the sentences and clauses are built in an almost identical grammatical construction. In that matter, parallelism actually involves a balance of different grammatical categories; for instance:
<em>My cat Greta enjoys sleeping on my bed, eating all the time and hunting bugs in the garden. In the same way, my dog Pepa loves taking long naps, waiting to be fed and going for walks.</em>
Thus, both sentences are written with the same structure: subject plus verbs followed by gerunds with <em>-ing</em>.
