inkling

I'm a little stuck... Click here to teach me more about this clue!

'suspicion' is the definition.
(an inkling is a suspicion or idea)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for inkling that I've seen before include "Slightest idea" , "Conception" , "Glimmer of understanding" , "Vague idea" , "Faint idea" .)

I've seen this clue in The Daily Express.
