Container of eggs nearly knocked over (3)
I believe the answer is:
tin
'container' is the definition.
(tin is a kind of container)
'eggs nearly knocked over' is the wordplay.
'eggs' becomes 'nits' (nits are insect eggs).
'nearly' means to remove the last letter.
'knocked over' is a reversal indicator.
'nits' with its final letter taken off is 'nit'.
'nit' written backwards gives 'TIN'.
'of' is the link.
(Other definitions for tin that I've seen before include "Element, symbol Sn" , "Silver-white element often used in food containers" , "Earnings" , "Light metal" , "Silvery-white metallic element" .)
