Names both sides of the Titanic? (5)
I believe the answer is:
terms
'names' is the definition.
(terming is a kind of naming)
'both sides of the titanic?' is the wordplay.
'both sides of' means to remove the middle letters (only the letters on the sides remain).
'titanic?' becomes 'RMS' (Titanic is an example).
'the' with its middle taken out is 'te'.
'te'+'rms'='TERMS'
(Other definitions for terms that I've seen before include "words" , "Conditions (contract)" , "Academic periods" , "Conditions, for school periods?" , "Stipulated requirements" .)
