How should I pronounce “LaTeX(2e)”?
Lamport never recommended how one should pronounce LaTeX, but a lot
of people pronounce it ‘Lay TeX’ or perhaps ‘Lah TeX’ (with
TeX pronounced as the program itself; see
the rules for TeX). It is definitely
not to be pronounced in the same way as the rubber-tree gum
(which would be ‘lay teks’).
The LaTeX2e logo is supposed to end with an
ε; nevertheless, most
people pronounce the name as ‘LaTeX-two-ee’.
