This is in the spirit of the What is a Word/Phrase™ series started by JLee with a special brand of Phrase™ and Word™ puzzles.


If a word conforms to a special rule, I call it a Dial Word™.
Use the following examples below to find the rule.

Dial Words™ Not Dial Words™
TAX DUES
MUD DUST
PAR EAGLE
DEAF DUMB
ONLY ONE
KITE SAIL
QUITS LEAVES
GLAZE SHINE
WINDOW DOOR
WINDOWS LINUX

And, if you want to analyze, here is a CSV version:

Dial Words™,Not Dial Words™
TAX,DUES
MUD,DUST
PAR,EAGLE
DEAF,DUMB
ONLY,ONE
KITE,SAIL
QUITS,LEAVES
GLAZE,SHINE
WINDOW,DOOR
WINDOWS,LINUX

I think that a Dial Word satisfies the property that

If we convert the letters of the word to numbers using the mappings of a telephone keypad we obtain a prime number

Examples

TAX $\rightarrow$ 829, which is prime
WINDOW $\rightarrow$ 946369, which is prime.
WINDOWS $\rightarrow$ 9463697, which is prime.
