Morphology

isochoric + process

The noun 'process' simply combines with an adjective in a fully compositional way, but the crucial element is 'isochoric', a technical adjective built from Greek roots (iso- 'equal/constant' + -choric relating to space/volume) that is not transparent to a B1 learner. Because understanding the phrase depends on specialist morphological knowledge or prior exposure to the adjective rather than everyday vocabulary, the expression is only partially predictable for typical learners.

Etymology

Isochoric process comes from the parts iso- (meaning 'equal') and choric (from a word for 'space' or 'room'), so it literally suggests 'equal space'. That's why an isochoric process means a process where the system's volume stays the same and does not change.
