Island with church on mountain, something like Cos (7)
I believe the answer is:
iceberg
'something like cos' is the definition.
I can't tell whether this defines the answer.
'island with church on mountain' is the wordplay.
'island' becomes 'i' (geographical abbreviation).
'with' says to put letters next to each other.
'church' becomes 'CE' (Church of England).
'on' means one lot of letters go next to another.
'mountain' becomes 'berg' (I've seen this before).
'i'+'ce'+'berg'='ICEBERG'
Can you help me to learn more?
(Other definitions for iceberg that I've seen before include "Kind of lettuce" , "smash hit in Titanic?" , "Floating piece from glacier" , "danger at sea" , "(Frozen?) type of lettuce" .)
