Majestic old lady meets daughter (5)
I believe the answer is:
grand
'majestic' is the definition.
(I've seen this before)
'old lady meets daughter' is the wordplay.
'old lady' becomes 'gran' (I've seen this before).
'meets' is a charade indicator (letters next to each other).
'daughter' becomes 'd' (genealogical abbreviation).
'gran'+'d'='GRAND'
(Other definitions for grand that I've seen before include "One thousand pounds" , "1,000 GBP" , "Comprehensive" , "Impressive, large" , "Stately - splendid" .)
