Morphology

Unbrako + key

Unbrako is a brand/proper name with no inherent lexical meaning for learners, while 'key' signals a tool, so a B1 learner who knows both words might infer this is some kind of tool made by Unbrako but cannot derive the specific sense 'hexagonal wrench for Allen screws.' The relation is partially transparent (tool + maker) but the precise technical meaning is unpredictable without exposure.

Etymology

Unbrako key comes from the Unbrako company that made strong six-sided bolts. The small L-shaped key fits into those bolt heads, so the name means 'a wrench for Allen or six-sided screws'.
