I’m newspaperman penning lines and reflection of it being inopportune (3-5)
I believe the answer is:
ill-timed
'inopportune' is the definition.
(similar in meaning)
'i'm newspaperman penning lines and reflection of it' is the wordplay.
'newspaperman' becomes 'ed'.
'penning' is an insertion indicator.
'lines' becomes 'll' (an abbreviation for line written twice).
'and' says to put letters next to each other.
'reflection of' shows that the letters should be reversed in order (I've seen 'reflection' mean this).
'it' written backwards gives 'ti'.
'im'+'ed'='imed'
'll'+'ti'='llti'
'imed' enclosing 'llti' is 'ILL-TIMED'.
'being' is the link.
(Other definitions for ill-timed that I've seen before include "Inopportune" , "Happening at a badly chosen moment" , "Done or occurring at an inconvenient moment" , "Badly scheduled" .)
