High seas retaining gooey substance for all time (7)
I believe the answer is:
ageless
'for all time' is the definition.
(belonging to all ages)
'high seas retaining gooey substance' is the wordplay.
'high' indicates anagramming the letters (can mean drunk or on drugs and hence disordered).
'retaining' is an insertion indicator (inserted letters are held or retained).
'gooey substance' becomes 'gel' (gel is a kind of substance. I am not sure about the 'gooey' bit.).
'seas' is an anagram of 'aess'.
'aess' placed around 'gel' is 'AGELESS'.
Can you help me to learn more?
(Other definitions for ageless that I've seen before include "not appearing to get old" , "Always youthful" , "Lasting a long time" , "Staying young" , "Eternally young" .)
