Sides with the things known to be true about open enterprise (6)
I believe the answer is:
facets
'known to be true about open enterprise' is the definition.
I can't judge whether this definition defines the answer.
'sides with the' is the wordplay.
'sides' becomes 'faces' (face is a kind of side).
'with' means one lot of letters goes inside another.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'faces' going around 't' is 'FACETS'.
'things' is the link.
Can you help me to learn more?
(Other definitions for facets that I've seen before include "Sides or aspects, diamonds or buildings" , "Sides of a cut gemstone" , "Faces of cut gemstones" , "Surfaces of a cut gem" , "Surfaces or aspects" .)
