Maybe halfway through acquiring something very small (6)
I believe the answer is:
midget
'very small' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for midget that I've seen before include "Dwarf" , "Happy for one" , "Manikin" , "Very small" , "Little person" .)
