How can i write a paragraph including the words sumptuous, parched, irresolute, odious, and stealthy

These are all great adjectives.  In order to use them, you need to know what they mean first.  If you already know that, come up with one or two items that you could use these adjectives for the description.  Stealthy is in secret and irresolute is uncertain, so you could write something like, "His stealthy personality left her feeling irresolute toward their situation."  Maybe work around that sentence?
