Label dish with game (7)
I believe the answer is:
hashtag
'label' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'dish with game' is the wordplay.
'dish' becomes 'hash' (hash is a kind of dish**).
'with' means one lot of letters go next to another.
'game' becomes 'tag' (tag is a kind of game).
'hash'+'tag'='HASHTAG'
Can you help me to learn more?
(Other definitions for hashtag that I've seen before include "Octothorp" , "Symbol used to indicate the subject of a Twitter message" , "Label on a Twitter post" , "component of tweet" , "Twitter mark" .)
