Morphology

intracellular + fluid

The phrase is directly compositional: 'intracellular' means 'inside cells' and 'fluid' means a flowing liquid, so together they denote the liquid found inside cells. Although somewhat technical, the meaning follows standard morphological composition (and parallels in other languages), so a B1 learner who knows both constituents would understand it.

Etymology

Intracellular fluid comes from intra- meaning 'inside', cellular meaning 'cell', and fluid meaning 'liquid'. So it is the 'liquid' that sits 'inside' each 'cell', which is why it means the liquid inside cells that helps them do their job.
