Obviously very friendly around quiet sailor (8)
I believe the answer is:
palpably
'obviously' is the definition.
(I've seen this before)
'very friendly around quiet sailor' is the wordplay.
'very friendly' becomes 'pally' (similar in meaning. I am not sure about the 'very' bit.).
'around' means one lot of letters goes inside another.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'sailor' becomes 'ab' (abbreviation for able seaman).
'p'+'ab'='pab'
'pally' placed around 'pab' is 'PALPABLY'.
Can you help me to learn more?
(Other definitions for palpably that I've seen before include "Without doubt" , "in touching way" , "obviously" .)
