Tiny hand may point to it (6)
I believe the answer is:
minute
I believe this is a triple definition!
'tiny' is the first definition.
(minute can mean small)
'hand' is the second definition.
(minute hand is a kind of hand)
'may' acts as a link.
'point to it' is the third definition.
'minute' can be an answer for 'point' (thesaurus). I'm not sure about the 'to it' bit.
Can you help me to learn more?
(Other definitions for minute that I've seen before include "Short period of time" , "not much time" , "Little -- 60 18 across" , "Barely perceptible" , "Measure of time" .)
