anglo

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

'english prefix' is the definition.
(I've seen this before)

'a long drawn' is the wordplay.
'drawn' is an anagram indicator (the letters drawn up in a different way).
'long' is an anagram of 'nglo'.
'a'+'nglo'='ANGLO'

'out' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.

Can you help me to learn more?

(Other definitions for anglo that I've seen before include "Prefix meaning English or British" , "Prefix denoting English" .)
