Tapering bodies with pointed sides (6)
I believe the answer is:
wedges
'tapering bodies' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps there's a link between them I don't understand?
'with pointed sides' is the wordplay.
'with' becomes 'w' (abbreviation).
'pointed sides' becomes 'edges' (edge is a kind of side. I am not sure about the 'pointed' bit.**).
'w'+'edges'='WEDGES'
Can you help me to learn more?
(Other definitions for wedges that I've seen before include "Shoves in between other objects, packs tightly" , "They taper from a thick to a thin end" , "Chunks" , "They taper to a thin edge" , "Thrusts or packs tightly among other things" .)
