lmao I've been working on and off all day trying to develop something that's effectively already been defined. Given how significant communal action is within pony society I thought a prefix for "togetherness" would be a great addition, but we already have the suffix -aft, "to do together"
I'll think on that a bit more, in the meantime I've got a couple more verbs

majen (v.) | to make
macian (OE - to make, do, cause, prepare, construct, transform). mag- (PIE - to fashion) source of makon (West Germanic - to fashion), makon (Old Saxon), makia (Old Frisian - to build, make), maken (Dutch), mahhon (OHG - to construct, make), machen (German).

Aight yeah, upon reflection I think this prefix works fine alongside -aft, in that they're not mutually exclusive. The prefix is ko- (together) which is pretty directly lifted from the proto-indo-european root which I sourced from my research into the root of “common” (ko-moin-i). I've used it to get words like

kogaerdin (adv.) | together, whole
etymology: togædere, geador (OE - together). ghedh- (PIE - to unite) source of gaduri- (Proto-Germanic - in a body).

komaenum (n.) | community, public interest, common ownership
etymology: gemænscipe (OE - community, union, common ownership), mæne (OE - common, public).

I also used it to augment the verbs I just listed. Perhaps it's too much, but I think it makes sense. The whole endeavor began with me trying to develop a word for "share", but its etymology is chiefly based in the noun as a remainder or product of division. The use I wanted to reference isn't used until later in history. So instead I pursued this route. Anyways, I wouldn't throw this prefix on every verb, but I think the following three have a lot of value

komajen (v.) | to collaborate, make together
kowegnen (v.) | to cooperate, participate
kogibten (v.) | to share, make even(edited)

dundra (v., n.) | (to) thunder, explode, yell, roar
dundrastoarm (n.) | thunderstorm

Are these accepted yet? Because I am working on 2 different things. A learning book, and a dictionary. The dictionary is more likely to be finished first.
hackd02/05/2018
I think some of them can be improved, but I haven't seen any feedback. I'd prefer they undergo some degree of review first
Also, I'd like to determine a convention for making verbs from nouns, and that would alter some of these
Hors3Atm02/05/2018
Yeeah, that would be nice. @TimeLoad you said something about a language reformation. Is that still relevant?
But until then I'm gonna add your words @hackd to my dictionary spreadsheet in Excel 2017. It is a WIP, but it is coming along nicely. They are gonna be in a "non verified" status.
hackd02/05/2018
I just did one more pass through them to fix up a couple things I've reflected on
Along with the verb/nouns, I'm not satisfied with saeswististoarm, swaem, and taefen(edited)
Hurricane and tornado were difficult since they're both Spanish words, and the English didn't really have their own words for them since they didn't experience that kind of weather(edited)
Aside from those exceptions, I think most of the suggestions are fairly robust, but I've included the etymology in case anyone wanted to use it to recommend changes
Also, I should say I prefer wult over vuht (forest), and med over eac (with), which were both what was previously suggested(edited)
