Subsequently catching start of Hollyoaks or frothy soap (6)
I believe the answer is:
lather
'frothy soap' is the definition.
'lather' can be an answer for 'soap' (I've seen this before). I am not sure about the 'frothy' bit.
'subsequently catching start of hollyoaks' is the wordplay.
'subsequently' becomes 'later' (subsequently means later on).
'catching' means one lot of letters goes inside another.
'start of' indicates taking the first letters.
The first letter of 'hollyoaks' is 'h'.
'later' enclosing 'h' is 'LATHER'.
'or' is the link.
Can you help me to learn more?
(Other definitions for lather that I've seen before include "starting to run in a sweat" , "Foam - tizzy (informal)" , "Panic" , "Soapsuds" , "Soapy froth" .)
