Does he ignore things in his log? (7)
I believe the answer is:
skipper
'does he' is the definition.
'Skipper' can be an answer for 'he'. I'm unsure of the 'does' bit.
'ignore things in his log?' is the wordplay.
'ignore' becomes 'skip' (I've seen this before).
'things in his log?' becomes 'per' (I can't justify this - if you can you should give a lot more credence to this answer).
'skip'+'per'='SKIPPER'
Can you help me to learn more?
(Other definitions for skipper that I've seen before include "Captain - small butterfly - fish" , "Shakespeare's giddy youth" , "delicate winger?" , "Ship's captain (colloq.)" , "Captain - one using a rope" .)
