Morphology
The phrase is a straightforward compositional noun phrase: the adjective 'triquetral' specifies which kind of 'bone' (a particular carpal/wrist bone), so the overall meaning is directly derivable from its constituents. Anatomical terminology commonly builds meanings by concatenating a specific descriptor with a general noun, making this predictable for learners who know both words.
Etymology
Triquetral bone comes from Latin: the part tri- means 'three' and the rest meant 'corner', so the name described a small 'three-cornered' bone. So, the name helps you remember it is the small triangular bone at the side of the wrist.
