How to extract text between multiple dashes?

[Gramlights]

Looking for a formula to extract text from between the 2nd and 3rd dash ("-").

Example: Create a formula to extract the word "pear"
apple-orange-pear-guava

But ONLY using the functions of MID, FIND, LEFT, RIGHT.

Note:
I'm able to come up with a formula to extract the word between the 1st and 2nd dash ("orange"), however I'm not quite sure how to manipulate the formula to achieve other nth extractions.
=MID(A1,FIND("-",A1,1)+1,FIND("-",A1,FIND("-",A1)+1)-FIND("-",A1)-1)

Thank you so much all!

A UDF makes this so much easier though

This sounds a lot like an assignment?

You already have the basic logic since you're using the third argument to FIND (the position to start the find from) but your formulas will be ugly.

Why make it yourself hard when you have better functions for this problem. Change the 3 in the formula below to get the nth extraction.

=SUBSTITUTE(MID(SUBSTITUTE("-"&A1,"-",REPT("@",50)),50*3,50),"@","")

Why make it yourself hard

Probably because it homework as Rory suggested.
