The noun 'der Hunger' (hunger) belongs to a word family with the adjective 'hungrig' (hungry, describing the feeling) and the verb 'hungern' (to go hungry / to suffer from hunger).
Nach einem langen Tag war er sehr hungrig.
After a long day, he was very hungry.
To express the physical feeling, German uses the fixed phrase 'Hunger haben' (to be hungry, literally: to have hunger). A person 'has' hunger in German; they are not hunger.

I haven't eaten anything since breakfast, and now I'm very hungry.
When 'Hunger' (hunger) describes a strong desire, it is almost always used with the preposition 'nach' and a noun in the dative. This pattern shows what the desire is directed toward.

He has an insatiable hunger for new knowledge.
In the meaning 'Hungersnot' (famine), 'Hunger' is often used without an article or in connection with geographic regions or crises. It then describes a social problem, not a personal feeling.

'der Hunger' and 'die Sehnsucht' can both express a strong desire. In this meaning, 'Hunger' often sounds active and strong, for example a hunger for knowledge or success. 'Sehnsucht' is usually more personal and emotional. It fits when something or someone is far away, lost, or hard to reach. The words can be confused because both express more than a normal wish. As a guide: 'Hunger nach' is more likely to fit goals and things you want to achieve. 'Sehnsucht nach' is more likely to fit people, places, or a state that you miss.
