Chapter one tense in true story (7)
I believe the answer is:
recital
'story' is the definition.
(thesaurus)
'chapter one tense in true' is the wordplay.
'chapter' becomes 'c'.
'one' becomes 'i' (Roman numeral).
'tense' becomes 't' (abbreviation used in many dictionaries).
'in' means one lot of letters goes inside another.
'true' becomes 'real' ('real' can be similar in meaning to 'true'**).
'c'+'i'+'t'='cit'
'cit' placed within 'real' is 'RECITAL'.
(Other definitions for recital that I've seen before include "gig" , "Telling" , "Public performance by a solo musician" , "Narrative" , "(Usually solo) concert" .)
