Morphology
This is a compositional adjective+noun: 'colloidal' specifies the kind of 'solution', so a learner who knows 'colloidal' (microscopically dispersed substances) and 'solution' (a liquid mixture) can infer it is a solution containing colloidal/suspended particles. While the precise technical distinction between dissolved vs. suspended may be specialized, the overall meaning is directly derivable from the constituents and follows a regular modifier+head pattern.
Etymology
Colloidal solution names a mixture where very small solid particles float evenly in a liquid, like tiny fat drops in milk. The word colloidal points to the tiny pieces and solution to the liquid, so the picture of bits that 'do not settle' helps you remember it means a liquid with particles that stay spread out and do not sink to the bottom.
