Defence and intelligence occupying two hospitals right now (9)
I believe the answer is:
forthwith
'right now' is the definition.
(thesaurus)
'defence and intelligence occupying two hospitals' is the wordplay.
'defence' becomes 'fort' (fort is a kind of defence).
'and' says to put letters next to each other.
'intelligence' becomes 'wit' (wit is a kind of intelligence).
'occupying' is an insertion indicator (inserted letters occupy or enter the word).
'two hospitals' becomes 'hh' (an abbreviation for hospital written twice. I am not sure about the 'two' bit.).
'wit' inserted within 'hh' is 'hwith'.
'fort'+'hwith'='FORTHWITH'
Can you help me to learn more?
(Other definitions for forthwith that I've seen before include "on the spot" , "without further delay - at which it starts, audibly" , "Without delay or hesitation" , "Immediately as with froth" .)
