Cricket, perhaps, popular with dedicated following (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
insect
'cricket perhaps' is the definition.
(cricket is an example)
'popular with dedicated following' is the wordplay.
'popular' becomes 'in' ('in' can mean trendy).
'with' is a charade indicator (letters next to each other).
'dedicated following' becomes 'sect' (I've seen this in another clue. I am not sure about the 'dedicated' bit.).
'in'+'sect'='INSECT'
Can you help me to learn more?
(Other definitions for insect that I've seen before include "E.g. cricket" , "Contemptible person" , "Worker, possibly" , "The entomologist studies this" , "Contemptible type" .)
