Specialist with logs put up a new platform (6)
I believe the answer is:
napier
'specialist with logs' is the definition.
I can't tell whether this definition defines the answer.
'up a new platform' is the wordplay.
'up' is a reversal indicator (in down clue: letters go upwards).
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'platform' becomes 'pier' (I have seen 'Coastal platform ' mean 'pier' so perhaps 'platform' could also mean 'pier').
'a'+'n'='an'
'an' in reverse letter order is 'na'.
'na'+'pier'='NAPIER'
'put' is the link.
Can you help me to learn more?
(Other definitions for napier that I've seen before include "NZ coastal city" , "Log producer" , "John --, Scottish mathematician" , "one bringing in logs" , "New Zealand port" .)
