Try and maybe hit a century in old-fashioned style (6)
I believe the answer is:
gothic
'old-fashioned style' is the definition.
'gothic' can be an answer for 'style' (I have seen 'Architectural style ' mean 'gothic' so perhaps 'style' could also mean 'gothic'). I am not certain of the 'old-fashioned' bit.
'try and maybe hit a century' is the wordplay.
'try' becomes 'go' (both can mean an attempt).
'and' means one lot of letters go next to another.
'maybe' is an anagram indicator.
'a century' becomes 'C' (common abbreviation).
'hit' with letters rearranged gives 'thi'.
'go'+'thi'+'c'='GOTHIC'
'in' is the link.
Can you help me to learn more?
(Other definitions for gothic that I've seen before include "Style between Romanesque and Classical" , "Of architecture with flying buttresses, for example" , "Describing some architecture" , "Early style of architecture and a literature dealing with mysterious events in eerie settings" , "See 6 ac" .)
