Do I seem upset about Royal Navy switch to new techniques? (9)
I believe the answer is:
modernise
'switch to new techniques?' is the definition.
I can't tell whether this defines the answer.
'do i seem upset about royal navy' is the wordplay.
'upset' indicates anagramming the letters.
'about' indicates putting letters inside.
'royal navy' becomes 'RN' (abbreviation for Royal Navy).
'do'+'i'+'seem'='doiseem'
'doiseem' with letters rearranged gives 'modeise'.
'modeise' enclosing 'rn' is 'MODERNISE'.
Can you help me to learn more?
(Other definitions for modernise that I've seen before include "to adapt to today's world" , "Make up to date" .)
