Morphology
The phrase is compositionally a noun phrase (a quark described as 'strange'), so a learner who knows 'strange' and 'quark' can infer it is a type or category of quark. However, 'strange' here names a technical quantum property (strangeness) rather than the ordinary sense 'unfamiliar', and the precise scientific meaning and properties (charge, mass, etc.) are not predictable from the constituents alone.
Etymology
Strange quark: The name strange quark comes from when scientists found particles that behaved oddly and kept their identity longer than expected, so they called that trait 'strangeness'. That's why the tiny particle was named strange (it carries 'strangeness') and the word quark was borrowed from a short line in a novel to name these basic building blocks of matter.
