The EA Hotel is now the Centre for Enabling EA Learning & Research (CEEALAR)

Some concrete problems I see with your choice:

• The name of an organization should ideally consist of two or three main words, perhaps four if there are strong enough reasons. Yours has six.
• The acronym formed by the name should ideally be pronounceable and aesthetically pleasing. I'm not sure CEEALAR is pronounceable. I don't think it's pleasing.
• The rules for generating the acronym should ideally be consistent. Either all articles and prepositions are included (e.g. CFAR) or none are (e.g. CEA). In 'Centre for Enabling EA Learning and Research', CEEALAR includes 'and' but excludes 'for'.
• [Note: Greg tells me that the name needs to be intelligible to the Charity Commission, so I retract this bullet point] The name need not provide a full description of the nature of the organization, or even be intelligible to newcomers. Those are desiderata, but may be trumped by other considerations. Consider, e.g., 80,000 Hours: no one would ever guess what they do just from the name alone, but it is still adequate, and much better than, say, Career and Coaching Services for Young Effective Altruists (CACSYEA).

I'll try to think of some concrete suggestions later, but all of Jonas's proposals look superior to CEEALAR, in my opinion. If you don't like the word 'Hotel' because of its for-profit connotations, how about replacing it with 'House'?

You may also want to consider creating a poll on an EA Facebook group, just like other EA orgs which went through a process of rebranding did in the past (e.g. Stefan Torges created one such poll a couple of months ago asking for alternatives to 'Foundational Research Institute').

I hope this doesn't come across as overly critical. Congratulations for putting in all the time and effort required to get the (former) EA Hotel registered as a proper charity!

EDIT: See also Ryan's comment [EA(p) · GW(p)].

I was thinking that you can always use a name that's different from the legal name. E.g., GiveWell's legal entity is called "The Clear Fund" but nobody cares/knows. Similarly, the Future of Humanity Institute has a "Centre for the Governance of AI" which isn't a separate legal entity. So it seems like the brand (and/or shorthand term) you use publicly is somewhat independent of the legal name.

I think it's worth noting that the acronym for the Athena Center for EA Study is ACES! :)

I like Rosie's suggestions (inspired by Jonas's).

Yep, that's it.

But I really think the whole name should be reconsidered.

You could keep the name but drop the first 'A': CEELAR. Excluding the 'A' of Altruism isn't great, but I think you're allowed to take major liberties with acronyms. And really, almost anything is better than CEEALAR.

Using the word "Hotel" is problematic as it's generally too associated with "for-profit" unfortunately. The other ideas you mention seem too generic; "Enabling EA Learning & Research" is a very concise summary of what we actually do. We didn't come up with anything better that was a pronounceable acronym.
