Rising tide for trendy fellow on base (6)
I believe the answer is:
inflow
'rising tide' is the definition.
'inflow' can be an answer for 'tide' (thesaurus). I'm unsure of the 'rising' bit.
'trendy fellow on base' is the wordplay.
'trendy' becomes 'in' ('in' can mean fashionable).
'fellow' becomes 'f' (abbreviation - of a society etc.).
'on' says to put letters next to each other.
'base' becomes 'low' (synonyms).
'in'+'f'+'low'='INFLOW'
'for' is the link.
Can you help me to learn more?
(Other definitions for inflow that I've seen before include "Movement inwards" , "Maybe immigrants" , "People arriving, say" , "Influx" , "entry?" .)
