Begin to grow first sign of grey fur around bare pate (9)
I believe the answer is:
germinate
'begin' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for germinate that I've seen before include "Start to grow - a regiment (anag)" , "Sprout - develop" , "(Of seed) start to shoot" , "Mere giant (anag) - start to grow" , "come to life" .)
