also: ラテフ
noun
LaTeX (document preparation system)
Refers specifically to the LaTeX typesetting system used in academic and technical publishing. The reading ラテック is standard; ラテフ is occasionally encountered but much less common.
論文はＬａＴｅＸで書きました。
I wrote my thesis using LaTeX.
ＬａＴｅＸの数式はとてもきれいです。
LaTeX equations are very beautiful.
TeX is the underlying typesetting engine; LaTeX is a macro package built on top of TeX that provides higher-level document preparation commands.
From the English 'LaTeX', a portmanteau of 'Lamport' (after Leslie Lamport) and 'TeX'. The Japanese pronunciation ラテック reflects the English /ˈleɪtɛk/ or /ˈlɑːtɛk/, while ラテフ may arise from a spelling-based pronunciation.
