Okra on table; first impressions - it's rubbery (7)
I believe the answer is:
gumboot
'impressions it's rubbery' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'okra on table first' is the wordplay.
'okra' becomes 'gumbo' (synonyms).
'on' becomes 'o' (I've seen this in other clues).
'table first' becomes 't' (1st letter of 'table').
'gumbo'+'o'+'t'='GUMBOOT'
Can you help me to learn more?
(Other definitions for gumboot that I've seen before include "Wellington" , "Waterproof footwear" , "Wader" .)
