Queen is pressing clergyman about missile carriers (7)
I believe the answer is:
quivers
'missile carriers' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'queen is pressing clergyman' is the wordplay.
'queen' becomes 'qu' (abbreviation for queen).
'pressing' means one lot of letters goes inside another.
'clergyman' becomes 'ver' (I am not sure about this - if you are sure you should believe this answer much more).
'is' enclosing 'ver' is 'ivers'.
'qu'+'ivers'='QUIVERS'
'about' is the link.
Can you help me to learn more?
(Other definitions for quivers that I've seen before include "Trembles" , "Cases for holding arrows" .)
