Etymology
From Ancient Greek παρέγχῠμα (parénkhŭma, “anything poured in beside”), from πᾰρᾰ- (pără-, “beside”) + ἔγχῠμα (énkhŭma, “instillation, content of a vessel”), given by the Greek anatomist Erasistratus to the peculiar substance of the lungs, liver, kidneys, and spleen, as if formed separately by the veins that run into them. By surface analysis, para- + -enchyma.
Meanings
-
(countable, uncountable) The functional tissue of an organ as distinguished from the connective and supporting tissue.

- (countable, uncountable) The cellular tissue, typically soft and succulent, found chiefly in the softer parts of leaves, pulp of fruits, bark and pith of stems, etc.
