Nurse extremely entertained by word for French artist (5)
I believe the answer is:
monet
'french artist' is the definition.
(I've seen this before)
'nurse extremely entertained by word' is the wordplay.
'extremely' suggests removing the centre (only the extremes of the word are used).
'entertained by' indicates putting letters inside (inserted letters are hosted or entertained).
'word' becomes 'mot' (I can't justify this - if you can you should believe this answer much more).
'nurse' with its middle taken out is 'ne'.
'ne' put into 'mot' is 'MONET'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for monet that I've seen before include "French artist shown in ..." , "Claude -, French artist" , "Giverny painter" , "French landscape painter" , "French impressionist (Waterlilies)" .)
