Filling in hole, a dentist's overbearing (6)
I believe the answer is:
leaden
'overbearing' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'filling in hole a dentist's' is the wordplay.
'filling in' says the answer is hidden in the clue.
'LEADEN' can be found hidden inside 'hole a dentists'.
Can you help me to learn more?
(Other definitions for leaden that I've seen before include "Heavy - overcast" , "Heavy and slow, as if weighted down with heavy metal" , "Describes grey overcast skies" , "Heavy - plodding" , "Gloomy - slow-moving" .)
