adjective
athirst
uh-THURST/əˈθɜrst/
Feeling a strong thirst.
Athirst after exertion, the adult eagerly reaches for a glass of water.

Etymology
The verb behind thirst already meant both needing drink and longing for something in Old English. Athirst preserves that connection: intense eagerness is expressed as a thirst.
