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 Single Word™.

Use the following examples below to find the rule.

Single Words™ Non Single Words™
water food
bear grizzly
beeswax honey
zebra horse
deer buck
rat mouse
cat feline
dad father
mom mother
you me

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

Single Words™, Non Single Words™
water, food
bear, grizzly
beeswax, honey
zebra, horse
deer, buck
rat, mouse
cat, feline
dad, father
mom, mother
you, me

  • $\begingroup$ Aw... I really thought that single words were words containing a letter with a different height from the others. $\endgroup$ Sep 23, 2016 at 17:38
  • $\begingroup$ @greenturtle3141 i didn't realize i was so close to fit with another rule! $\endgroup$

A Single Words™ looks like one which

Is typed using just one hand with a standard keyboard touch typing method

Left hand letters are Q, W, E, R, T , A, S, D, F, G , Z, X, C, V, B

Right hand letters are Y, U, I, O, P , H, J, K, L , N, M

enter image description here

And the Non Single Words™ need both hands to touch type.

I'm not at all sure that I understand the rationale, but, a Non Single word is

one that contains at least one of the letters f, g, h, i, j, k, l and/or n,
and/or contains both letters m and e.

A Single word, obviously, is one that does not conform to the above rule.

My best guess is that it has something to do with the first-person singular pronouns, "I" and "me" — something like

it's not single if I'm there with it
The letters f, g, h, i, j, k, l and n are the letters between e and o, which are the last vowel before i and the first vowel after i.

Yes, I know there are no words in the table that contain j.  Or p, q, or v.  I assume that's just to avoid making it too easy.
