Morphology
The phrase is compositionally built from 'azo' + 'group' — i.e. a group characterized by an azo functional unit — so the structure follows standard chemical naming patterns. However, 'azo' is a technical/bound morpheme referring specifically to an –N=N– linkage and is not predictable from general vocabulary, so a B1 learner without chemistry background would likely need extra domain knowledge.
Etymology
The term azo group comes from the old word 'azote' for nitrogen, whose Greek roots meant 'no life' because nitrogen gas does not help you breathe. An azo group is the small piece –N=N– (two nitrogen atoms joined), so the name points to that nitrogen link and helps you remember why many dyes with an azo part are brightly colored.
