Climbs aboard, soon to find what one's seeking? (6)
I believe the answer is:
swarms
'climbs' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their -s form.
Maybe there's an association between them I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for swarms that I've seen before include "Dense groups of flying insects" , "Large groups of flying bees" , "'Moving crowds, of bees say (6)'" .)
