Gather some flowers (5)
I believe the answer is:
bunch
'gather' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bunch that I've seen before include "Small number of flowers tied together" , "Group of people (informal)" , "Cluster (of grapes)" , "Gang" , "Show silly fondness" .)
