Innovative printer’s instinctive vigour, mostly about book (9)
I believe the answer is:
gutenberg
'innovative printer's' is the definition.
'gutenberg' can be an answer for 'printer's' (I've seen this before). I'm not certain of the 'innovative' bit.
'instinctive vigour mostly about book' is the wordplay.
I cannot quite see how this works, but
'instinctive' could be 'gut' (as in a gut feeling) and 'gut' is located in the answer.
'book' could be 'b' (abbreviation for book) and 'b' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for gutenberg that I've seen before include "He invented movable-type printing" , "Publisher" , "German printing pioneer" , "Pioneer printer" , "German printer of a 15th century Bible" .)
