Don't disappear as English join forces (6)
I believe the answer is:
emerge
'don't disappear' is the definition.
I can't tell whether this defines the answer.
'english join forces' is the wordplay.
'english' becomes 'e' (abbreviation).
'join' says to put letters next to each other.
'forces' becomes 'merge' (I can't justify this - if you can you should give a lot more credence to this answer).
'e'+'merge'='EMERGE'
'as' is the link.
Can you help me to learn more?
(Other definitions for emerge that I've seen before include "Become known or apparent" , "Move out and become visible" , "Rise to notice" , "(Of facts) become known" , "Issue" .)
