What is a feminine version of 'guys'?

Solution 1:

“Guys” can be used in English as gender neutral to refer to a group of mixed gender.

You will even hear women refer to other women as “guys.”

The closest linguistic equivalent with a feminine tilt would be “gals.” “Guys and gals” is a rather informal variant of “ladies and gentlemen.” (Note the reverse order.)

Edit: As noted by @kitukwfyer in the question comments, it is possible for “gals” to be derogatory when used by itself so be careful. It’s not likely to be a problem used in the pairing above. Used carefully it’s probably safe, but used by itself it could be heard as mockery.

Saying the following is unlikely to offend anyone:

“The gals talked in the kitchen while the guys went out to see Fred’s new truck.”

But walking up to a couple women on a street corner and saying this might get a strange reaction:

“Excuse me gals, where is the grocery store?”

Saying this to a couple girls might make them doubt you:

“Hey gals come with me.”

But if you are explaining some game instructions and say the following it’s likely to be fine:

“Alright, guys on this side of the room, gals on the other.”

Solution 2:

I often use folks when addressing a group, both in public speaking and in email. Admittedly, it is a bit, er, folksy for business email, but it saves me time in thinking about the issue.

Edit: another informal term is gang. For email, I would only use this for colleagues within my department or team, and not to those outside of the team. e.g. "Hey gang, remember that the server is being rebooted tonight."

Solution 3:

Especially in these rapidly changing times, we must be careful not to make false assumptions about our addressees.

For this reason, it’s important to use broad, inclusive appellations like sentient life forms and beings.

If there is a chance that one or more of the group members may have ceased to be by the time your utterance has been processed, you should use the term entities or conceptual units. If all bets are off, you can’t fail to address the addressees appropriately and correctly with the term addressees.

Canadians is also universally acceptable.

Solution 4:

Gals comes to mind, as in the commonly used expression guys and gals.

Solution 5:

You can also use guys to address a group of women. See my response to the question "What is the possessive of 'you guys'?"
