Hook it to a bit of current after the odd drench (6)
I believe the answer is:
decamp
'hook it to a bit' is the definition.
I can't tell whether this defines the answer.
'current after the odd drench' is the wordplay.
'current' becomes 'amp' (electricity).
'after' says to put letters next to each other.
'the odd' indicates alternate letters.
The alternating letters of 'drench' are 'dec'.
'amp' after 'dec' is 'DECAMP'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for decamp that I've seen before include "Fold tents and go" , "Run away (from responsibility)" , "Fold up tent and depart" , "Do a runner" , "Bolt" .)
