Covering grand, dear! (5)
I believe the answer is:
glove
'covering' is the definition.
(glove is a kind of covering)
'grand dear' is the wordplay.
'grand' becomes 'g' (G is short for grand as in a thousand).
'dear' becomes 'love' (synonyms).
'g'+'love'='GLOVE'
(Other definitions for glove that I've seen before include "Noisy disturbance" , "hands warmer" , "Hand in this is very closely associated" , "Hand cover" , "On-hand children's entertainer?" .)
