Meet corgi, moving using straight lines (9)
I believe the answer is:
geometric
'using straight lines' is the definition.
I can't judge whether this definition defines the answer.
'meet corgi moving' is the wordplay.
'moving' is an anagram indicator (letters are moved around).
'meet'+'corgi'='meetcorgi'
'meetcorgi' is an anagram of 'GEOMETRIC'.
Can you help me to learn more?
(Other definitions for geometric that I've seen before include "Sort of progression" , "Decorated with regular shapes" , "Characterised by lines, points and surfaces" , "regular patterns" , "with great regularity" .)
