Ginger gets glasses at the going rate (5)
I believe the answer is:
oomph
'ginger' is the definition.
(I've seen this before)
'glasses at the going rate' is the wordplay.
'glasses' becomes 'OO' (OO looks like spectacles).
'at' means one lot of letters go next to another.
'the going rate' becomes 'mph' (mph is a kind of rate. I am not sure about the 'going' bit.).
'oo'+'mph'='OOMPH'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for oomph that I've seen before include "Exciting energy" , "drive" , "Vitality - sex appeal (informal)" , "Get-up-and-go" , "Go" .)
