I go and call afresh, being reasonable (7)
I believe the answer is:
logical
'reasonable' is the definition.
('logical' can be similar in meaning to 'reasonable')
'i go and call afresh' is the wordplay.
'and' says to put letters next to each other (I've seen this in other clues).
'afresh' is an anagram indicator.
'i'+'go'='igo'
'igo' after 'call' is 'calligo'.
'calligo' with letters rearranged gives 'LOGICAL'.
'being' is the link.
(Other definitions for logical that I've seen before include "Based on reason" , "Well-reasoned" , "In accordance with reason" , "Well thought out" , "Showing rational thought" .)
