Titanic’s report about replacing missing individual (7)
I believe the answer is:
massive
'titanic's' is the definition.
(thesaurus)
'report about replacing missing individual' is the wordplay.
I cannot quite see how this works, but
'about' could be 'a' (abbreviation in Chambers) and 'a' is present in the answer.
'individual' could be 'ms' (Ms. is an example) and 'ms' is present in the remaining letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for massive that I've seen before include "Monolithic, huge" , "Imposing in size" , "Enormous" , "Bulky, weighty" , "Gargantuan" .)
