The story

Potentially a borrowing from Ancient Greek λᾰ́τᾰξ (lắtăx, “drop of wine”), reformed by analogy to other nouns in -ex. The semantic shift, however, from drop of wine to water is difficult to explain and may indicate that both words originated from a separate language.

Today it means

noun A clear liquid believed to be a component of a humour or other bodily fluid (esp. plasma and lymph).

Language periods are conventional ranges, not dates for this word.
