Do Ponies speak English or do they have their own language?

I think they speak English: if I remember correctly there have been some English words written on banners, and they know the word "French"...

I would say they speak english. If they had their own language then twilight would be completely incomprehensible to all humans in Equestria Girls (also spike wouldn't exactly a "talking" dog, just a weird dog whose barking is reminiscent to horse sounds).

 

tho an equestrian language would be cool, it would just make more sense if they spoke english.

Okay, I think most of the ponies speak English because it's a show made by a US company but then there's Zecora! She's interesting because in one episode she spoke something that sounded very much like

which, incidentally, was the same native language Lieutenant Uhura spoke in the original Star Trek series. I don't know about anyone else but I can hear distinct similarities to what Zecora speaks in

Id say they have an own language for you can see their strange hyroglyph like writing in the very first episode.

...No. I personally think it is indeed English they are speaking.

I believe that the citizens of Equestria speak a language called Ungulish. The origins of this language come from a place named Unguland, a kingdom on an island that merged with a bunch of other kingdoms.

What was the episode where Celestia (I think) said something was written in "old Ponish?"

Also, the comics have a lot of written words and puns in the background, on signs, etc. I wonder if the non English comics have those things changed.

So it seems they write English.

They do have their own language, but remarkably, their language sounds exactly like English.
