remove from the matrix any pairs of letters so

N L L R L N A

would become

Got it. Here's the updated matrix with all pairs of letters removed:

A    O    A    Y         L
L         N         V
I    O    A         P    M
G         P              A
O              O         Z
                    R

And the string "NLLRLNA" has been reduced to "RLA".

from the remaining letters what words or phrases can be created by combining the remaining letters in any way that fits.

Here are some words and phrases that can be created from the remaining letters in the matrix:

1. AMIGO
2. OIL
