Morphology

truth + quark

Although the words 'truth' and 'quark' are individually understandable, the term 'truth quark' is a technical/historical label for the top quark and its specific properties (charge, very large mass) are not derivable from the literal meaning of 'truth'. A B1 learner who knows the constituents would not predict the specialised particle identity or properties from the parts, so the expression functions as an arbitrary technical name rather than a compositional phrase.

Etymology

Truth quark started as an early name scientists used for the heaviest quark; they chose truth to suggest it was the 'true' or most important match to another quark called 'beauty'. Later the shorter name 'top quark' became standard, so truth quark is just an older name for the same heavy particle.
