I believe the answer is:

rattles

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

'makes a noise' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their -s form.
Perhaps there's a link between them I don't understand?

'order to startle?' is the wordplay.
'order to' indicates an anagram (a different order to the letters).
'startle' anagrammed gives 'RATTLES'.

'in' is the link.

Can you help me to learn more?
