I'm a little stuck... Click here to teach me more about this clue!

'tom in paris maybe set up secure' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'online space' is the wordplay.
'online' becomes 'chat' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'space' becomes 'room' (room is a kind of space).
'chat'+'room'='CHAT ROOM'

Can you help me to learn more?

(Other definitions for chat room that I've seen before include "space for communication" , "With PC talk here" , "place for online gossip" , "Internet forum" , "Online space where people can meet and talk" .)
