What is the meaning of "te"?

It’s my understanding that the name “Jupyter” is taken from the languages Julia, Python, and R i.e., Ju-Py-te-R. If so, what language is Te? Or, is it just Tea?

I always thought it came from ‘terminal’ with the R doing double duty. However, this slide from Fernando Perez’s 2014 slide deck clearly mentions only those languages and that arranging the letters then borrowed those two letters to round things out, incorporating a play on ‘Jupiter’ from Astronomy.
