Seen staggering round the bend so as to follow (5)
I believe the answer is:
ensue
'to follow' is the definition.
(ensue can mean to follow or happen as a result)
'seen staggering round the bend' is the wordplay.
'staggering' is an anagram indicator (letters stagger around).
'round' indicates putting letters inside.
'the bend' becomes 'U' (a U-bend is a kind of bend - pipe under sink).
'seen' is an anagram of 'ense'.
'ense' enclosing 'u' is 'ENSUE'.
'so as' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for ensue that I've seen before include "Leading directly to" , "Occur afterwards" , "Come next" , "succeed" , "Happen afterwards as a result" .)
