Grammar police: Is it "Dos and Don'ts" or "Do's and Don'ts?"

[Auggie]

I'm seeing it two ways. "Dos and Don'ts" seems correct to me.

Thanks for helping

1. Dos and don'ts, not Do's and don'ts

The apostrophe s is only for possessive cases.

On edit: Well, possessive cases and a contraction of is. But "dos" is neither of those.

2. Dos and don'ts

There's also no apostrophe between a year and an S at the end. Correct: '70s; incorrect: 70's.

4. People do such amazing things with apostrophes

(That's "apostrophes" and not "apostrophe's")

I was reading a post on another board the other day which was just sprinkled with redundant apostrophes. I think a lot of people put them in whenever they end a word in an "s" but this person was putting them in and leaving them out with about equal frequency - every now and then, it would be correct.

It was sort of dizzying to read.

5. From the grammar book "Woe Is I"

My grammar book "Woe Is I" included a poem to help illustrate these odd plurals:

Words to the Whys

Ups and downs and ins and outs,
Forevers and nevers and whys.
Befores and afters, dos and don’ts,
Farewells and hellos and good-byes.
Life is a string of perhapses,
A medley of whens and so whats.
We rise on our yeses and maybes,
Then fall on our noes and our buts.

7. As long as you mind your ps and qs

It's really not a big deal.

Named "Doggie Dos" and "Doggie Dos and Don'ts"
