'Pre-Processing / Formatting Data

I have two vectors in R:

     list1 <- c("ABCDEF", "FEDCBA", "AA-BB-CCCC", "ABCDEFGH-IJK", "ZZZZ")
     
     list2 <- c("ABCDEF", "FEDCBA:XA",   
   "AA-BB-CCCC-01","AA-BB-CCCC-21:ABC", "ABCDEFGH-IJK-1X",   
   "AKDWXFE-XXY")

I'd like to compare the two lists -- with list1 being the 'correct' list. If an item in list1 does not appear in list2, then print out 'Add [item in list1]'; if item in list2 is not in list1, then print out 'delete [item in list 2]'. I would like to find partial matches. For example, list 1 has 'FEDCBA' and list2 has 'FEDCBA:XA" -- this would be an acceptable partial match....same with list 2 having AA-BB-CCCC-21:ABC while list1 has AA-BB-CCCC (this is also an acceptable partial match).
