Morphology

sodium + thiosulfate

This is a systematic chemical name: 'sodium thiosulfate' literally denotes the sodium salt/compound of the thiosulfate anion, so a learner who knows 'sodium' and 'thiosulfate' can predict it is a specific chemical compound. While detailed uses or properties require domain knowledge, the basic referent (a sodium-containing thiosulfate compound) is compositionally derivable and cross-linguistically transparent via chemical nomenclature.

Etymology

Sodium thiosulfate is a lab name made of clear parts: sodium is the metal in common salt, thio is a short label chemists use for 'sulfur', and sulfate shows it is a type of salt. So the name helps you remember it is a white salt that dissolves in water and is used to 'fix' photos and to treat some poisonings.
