Morphology
The constituents 'methyl' (a chemical group) and 'orange' (a color) make it reasonable for a learner to infer this refers to an orange-colored chemical substance, so the colour and chemical nature are transparent. However, the specific technical sense — an azo dye used as an acid–base indicator in titrations — is specialized and not predictable from the parts alone, making the full meaning only partially recoverable.
Etymology
Methyl orange comes from the small chemical part methyl and the dye's bright color orange. That's why the name fits this orange dye used to show whether a liquid is an 'acid' or a 'base'.
