Hello,

Sorry for a questioin that is a bit off-topic.

I'm a bit confused about the TeX terminology. I know what is what, but I don't know how all these programs/packages/macros are officially called in English.

How would you explain those in an encyclopedy with no more than one sentence?

* plain TeX, LaTeX, ConTeXt are ... ? TeX formats ? (but ConTeXt is not just that)

I would say plain and latex are 'TeX macro packages'. ConTeXt is more like a 'typesetting system with TeX and MetaPost at it's core'

* TeX, eTeX, pdf(e)TeX, Aleph, Omega, XeTeX are ... ? TeX engines/extensions, an extended version of TeX ?

Variants?
