A lot of water in a fissure on the hill (7)
I believe the answer is:
torrent
'a lot of water' is the definition.
I can't tell whether this defines the answer.
'a fissure on the hill' is the wordplay.
'a fissure' becomes 'rent' (both can mean a rip or rift).
'on' says to put letters next to each other.
'the hill' becomes 'tor' (tor is a kind of hill).
'rent' after 'tor' is 'TORRENT'.
'in' is the link.
Can you help me to learn more?
(Other definitions for torrent that I've seen before include "Fast-moving stream" , "Heavy rain" , "Great stream" , "Overwhelming flood" , "A rushing stream of water" .)
