Revere rear-facing paddle on large boat (7)
I believe the answer is:
'revere' is the definition.
(I know that revere can be written as worship)
'rear-facing paddle on large boat' is the wordplay.
'rear' says the letters should be written backwards (I've seen 'rearing' mean this (as in a horse rearing up)).
'facing paddle on' becomes 'row' (I can't justify this - if you can you should believe this answer much more).
'large boat' becomes 'ship' (I've seen this before).
'row' in reverse letter order is 'wor'.
Can you help me to learn more?
(Other definitions for worship that I've seen before include "Adore, venerate" , "idolisation" , "Religious devotion" , "religious service" , "Devotions" .)
