Woe and ill makes you stay hidden (3,3)
I believe the answer is:
lie low
'stay hidden' is the definition.
(I've seen this before)
'woe and ill makes' is the wordplay.
'and' means one lot of letters go next to another.
'makes' indicates an anagram.
'woe'+'ill'='woeill'
'woeill' is an anagram of 'LIE LOW'.
'you' acts as a link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for lie low that I've seen before include "avoid detection" , "Conceal oneself in recumbent posture?" , "Avoid attracting notice" , "Keep concealed or quiet" , "Stay quiet and/or hidden" .)
