Giant relations wearing brown (5)

Ross

I believe the answer is:

titan

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

'giant' is the definition.
(I know that giant can be written as titan)

'relations wearing brown' is the wordplay.
'relations wearing' becomes 'ti' (I can't explain this - if you can you should give a lot more credence to this answer).
'brown' becomes 'tan' (tan is a kind of brown).
'ti'+'tan'='TITAN'

Can you help me to learn more?

(Other definitions for titan that I've seen before include "Atlas, say" , "one of great importance" , "Huge(ly important) type" , "Giant god of Gr. myth" , "Moon of Saturn visited by the Huygens probe" .)
