Trifling - like a naval officer? (5)
I believe the answer is:
This might be a double definition.
'trifling' is the first definition.
(I've seen this before)
'a naval officer?' is the second definition.
'petty' can be an answer for 'officer?' (petty officer is a kind of officer). I am not certain of the 'a naval' bit.
'like' acts as a link.
Can you help me to learn more?
(Other definitions for petty that I've seen before include "Trivial, contemptible", "Trivial - small-minded", "Inferior", "Marked by narrowness of mind", "Insignificant and smallminded".)
