Make a DOS batch script to rename between word of files

Question

I'm currently stuck on an issue with a DOS batch script I’ve been working on, and I need help renaming the files.

Here is the renaming scheme I’m searching for:

Original filenames are more than 30. I wrote only 4.
For example, what do I do for put "kyt-" before last words?

all file name : pajiro kart 05 abd.txt

results: : pajiro kart 05 kyt-abd.txt

or

all file name : pajiro kart 05 acd.txt

results: : pajiro kart 05 kyt-acd.txt
