Become friendly with me and an officer (4)
I believe the answer is:
melt
'become friendly' is the definition.
I can't judge whether this definition defines the answer.
'me and an officer' is the wordplay.
'and' says to put letters next to each other.
'an officer' becomes 'lt' (I've seen this in other clues).
'me'+'lt'='MELT'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for melt that I've seen before include "Become liquefied" , "Calm" , "Reduce from a solid to a liquid state" , "Dissolve with heat" , "Thaw" .)
