'Die Ahnung' (hunch/idea) belongs to the word family of the verb 'ahnen' (to suspect/sense), which means 'to feel or suspect something vaguely.' An 'Ahnung' is therefore the feeling or suspicion itself.

Ahnung vs Gefühl
feeling / sense
'das Gefühl' and 'die Ahnung' can both mean an uncertain inner suspicion. 'Gefühl' is more general: you can have a feeling that something is right or not right without knowing exactly why. 'Ahnung' is more strongly connected to a suspicion or premonition. It often means that you vaguely expect something or have a vague idea. The fixed expression 'keine Ahnung haben' is also important; it means that you do not know something. Learners may confuse the words because both can express uncertain knowledge. As a memory aid: 'ein Gefühl haben' is more intuitive, while 'eine Ahnung haben' is more of a vague suspicion or limited knowledge.
