Do the Borg have a language?

Question

I just realised something, with the amalgamation of species and cultures into the Borg, what language do they speak? I see three options but I can't find evidence for any:

1. The Language of Species 0001
2. The most efficient language they've found so far
3. Whichever language they need to use at the time

And we hear English via the UT.

I can't see number one being popular, nor can I see 2 being helpful when they have to update documentation...

I'm stumped. Is there another, better, more correct answer? Which one is it? Can we know?

edit

I'm mostly interested in the times they speak to other species, however infrequently that is.

Answer 1

As far as I understand the Borg, they don't use any language to communicate. They are a collective mind and are aware of each other's thoughts, presumably without the requirement for a language. However, at this point everything gets a bit esoteric; Can we think without language? If not, how are thoughts carried inside the brain?

Anyway, when communicating with non-Borg, spoken communication falls under the general "how do different species talk to each other" wibbly-wobbly. If the Borg Queen talks to Picard and Data in First Contact or to Janeway in Endgame they are either speaking English or one of the languages you list. With each other, they don't require a spoken language.

This is evidenced by the Borg Queen in First Contact referring to language as primitive communication:

BORG QUEEN: Why do you insist on utilising this primitive linguistic communication? Your android brain is capable of so much more.

Answer 2

The use what, to me, sounds like a form of very complex computer code as their language. Due to the link to the collective, all drones know it upon assimilation:

the Borg used alphanumeric code as their written language and for encoding and transmitting data throughout the Collective. Their language consisted of circular symbols with geometric shapes cut out of them. These symbols could be seen on various control panels, labels, and viewscreens within Borg structures. It was written in many different directions: in horizontal lines going from left to right and right to left, and vertically. As the name suggests, the symbols represented both alphabetic characters that represented sounds, and numbers, with much Borg terminology comprising alphanumeric sequences.

The code was immensely complex and consisted of at least fifty characters and was stored, among other places, in data nodes. Despite its complexity, other species could learn it. (VOY: "Revulsion")

And from about 11 and a half minutes into VOY 4x01, Scorpion Part II, this screenshot - look at the blue circles for an example of Borg written language (they change as the scene goes on):
