Morphology
arsenous + anhydride
The phrase is compositionally built from a modifier meaning 'related to arsenic' (arsenous) and a chemical class term (anhydride), so a learner who knows both constituents can infer it denotes an anhydride of an arsenic-containing acid — i.e., an arsenic-derived chemical compound. Chemical naming conventions are cross-linguistically regular, making the overall meaning predictable from the parts rather than idiomatic.
Etymology
Arsenous anhydride comes from two parts: arsenous meaning 'related to arsenic' and anhydride meaning 'without water', so the name points to a dry form of arsenic. That's why the word refers to the white, poisonous powder used in glass making and pesticides.
