By using brash diction like "crone" and "pig" Homer demonstrates that Irus is a bitter, ungrateful person

By using strong diction like wily, Homer is able to demonstrate how experienced and skilled Odysseus is when faced with difficult situations.

Homer includes diction such as "hulk" to present Odysseus as a strong character, both mentally and physically, as Odysseus is encountered with tests along his journey that require this kind of idiosyncrasy.

By using the diction "tramp" Homer suggests that the character Irus is a territorial, surly man.
