We do not.

For what is intended to be cohesiveness and ease of use, previous individual entries for suffixes have been combined into one suffixes entry. Same with prefixes. Unfortunately, searching for an individual prefix or suffix doesn't take you immediately to the umbrella entry. I'm asking if there's a way to fix that. In the meantime, from the suffixes entry:

-like Generally no hyphen unless the letter l would be tripled or the main element is a proper noun. Examples: businesslike, catlike, childlike, doglike, lifelike. But: Norwalk-like, shell-like. An exception: flu-like.

The comma is needed if Emma is his only wife (presumably, she is). If Jordyn is their only daughter, the comma is needed. In those cases, the names are nonessential phrases and thus a comma is necessary.

If they have more than one daughter (let's say, Jordyn and EmmaSue), then the name becomes an essential phrase and no comma is used.

I know this sounds confusing! Details are in the essential phrases, nonessential phrases entry.

A group ... has proposed. Yes, the subject is group and that dictates the singular verb.

I stand corrected. We will still fall in line with Merriam-Webster. Even though I don't agree on this one! I'll correct the answer from the other day. Thanks.

That looks good to me!

We don't have a stance on that.

Depends on local or common usage. There's no rule. 

This isn't spelled out in the entry, but here's what we do in practice: If the region is commonly referred to as, for instance, the Greater Boston area, then capitalize Greater. If it's more a one-off or limited description for that particular region, use the lowercase. And yes, always lowercase area.

We don't have a position on that. We see it as more an individual stylistic choice. Using the comma provides a mental break and a bit more emphasis on the too. 

Either is commonly used, but I'd go with all-expenses-paid as a modifier.

CORRECTED: face-to-face, with hyphens, in all uses. This follows Merriam-Webster's style. 
Or: They met in person.

I'd use the hyphen.

Single quotation marks.

We don't have written guidance. But we agree in principle that the "or not" isn't necessary. 

Depends on whether those are recognized as, in effect, common nouns for those neighborhoods. Such as Midtown Manhattan. We'd almost certainly lowercase downtown in all uses, unless there's a clear local argument otherwise. The midtown/Midtown descriptor is more variable.

Here's the party affiliation entry.

We have one style; Merriam-Webster has another. Either can be correct. Choose the one you prefer. (We are generally, but not always, in synch with our primary dictionary. That's always been the case.)

We use the style Day 1. Merriam-Webster uses day one. Either is correct; it's a matter of which style you prefer. We don't always align 100% with our primary dictionary. That's always been the case. 

No hyphen. Here's the guidance from the millions, billions, trillions entry.

We don't do that in AP style. Other style guides might call for it in some types of writing. There's no "correct" usage. It's a matter of which style you follow.

Sorry, but we don't have a style for the periodic table. 

The latter.

That's fine. 

It's sub-Saharan, following this unchanged guidance from the prefixes entry: 

Three rules are constant:

And: semisubmersible. Merriam-Webster hyphenates jack-up for the rig and we will follow the dictionary lead on that.
