Every year when climbing, Scotsman connected with colonist perhaps (5)
I believe the answer is:
apian
'connected with colonist perhaps' is the definition.
I can't tell whether this definition defines the answer.
'every year when climbing scotsman' is the wordplay.
'every year' becomes 'pa' (per annum).
'when climbing' shows that the letters should be reversed in order.
'scotsman' becomes 'ian'.
'pa' reversed gives 'ap'.
'ap'+'ian'='APIAN'
Can you help me to learn more?
(Other definitions for apian that I've seen before include "Relating to bees" , "Concerning bees" , "Concerning 27 across" , "social worker described thus?" , "concerning stingy types" .)
