I believe the answer is:

proper

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

'real' is the definition.
('proper' can be similar in meaning to 'real')

'support on english right' is the wordplay.
'support' becomes 'prop' (prop is a kind of support).
'on' says to put letters next to each other.
'english right' becomes 'er' (this might be a standard abbreviation which I don't know about).
'prop'+'er'='PROPER'

Can you help me to learn more?

(Other definitions for proper that I've seen before include "Right, correct or appropriate" , "part of Mass" , "Real; genuine" , "Correct; respectable" , "Genuine; suitable" .)
