Someone likely to have some Sega merchandise (5)
I believe the answer is:
gamer
'someone likely to' is the definition.
I can't judge whether this defines the answer.
'some sega merchandise' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'GAMER' is hidden in the letters of 'sega merchandise'.
'have' acts as a link.
Can you help me to learn more?
(Other definitions for gamer that I've seen before include "Keen computer player" , "I bet" , "More handicapped" , "More spirited" , "One role-playing on computer" .)
