I need help with an IF-AND formula

I need help in creating a formula (in Google Sheets) which concatenates three cells of data together in a specified order indicated by two dropdown boxes. Below is a picture of my test spreadsheet.

I would like assistance in writing a formula in the result cell which has the following results:

Auxiliary-Root-Affix IF B1="Pre-verb" AND B2="Suffix"

Auxiliary-Affix-Root IF B1="Pre-verb" AND B2="Prefix"

Root-Affix-Auxiliary IF B1="Post-verb" AND B2="Suffix"

Affix-Root-Auxiliary IF B1="Post-verb" AND B2="Prefix"

I'm a conlanger if you couldn't tell :P .
