Morphology

ground + substance

Although the phrase combines 'ground' and 'substance', the everyday senses of 'ground' (soil, earth) and 'substance' (material) do not transparently yield the specialized biological sense of a clear, non-granular matrix in the cytoplasm. This is a domain-specific technical term whose meaning requires subject knowledge rather than simple composition, so a B1 learner who only knows the constituents would likely misinterpret it.

Etymology

Ground substance comes from the image of ground as the 'base' and substance as the 'material', like soil that holds roots and stones. So, like soil holding plants, ground substance is the soft material that holds cells and fibers in connective tissue.
