Great solve, michele!

I knew one answer and had to confirm that the second 'insert' was actually potentially part of the set.
I will have to spend a bit more time trying to winkle out the other two.
So at this stage its half a solve and might help others

3. polygraph (lyra)
facetious (cetus)

I think I know one of the words for #4 but I can't figure out any others at all to see if I can come up with a related set.

4

subclauses - class
coriander - order
spermicides - species

OB, well done!

I had only coriander. I was working with house but never even got the green part.
