Pass an old invader poorly (2,7)
I believe the answer is:
go through
'pass' is the definition.
The definition and answer can be both to do with contact as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'old invader poorly' is the wordplay.
'old invader' becomes 'goth' (I've seen this before).
'poorly' becomes 'rough' (I can't justify this - if you can you should believe this answer much more).
'goth'+'rough'='GO THROUGH'
'an' acts as a link.
Can you help me to learn more?
(Other definitions for go through that I've seen before include "Face" , "be accepted" , "brave" , "Suffer from" , "Use up - experience" .)
