Morphology
stannous = stann + ous
The combining form 'stann-' is a Latin stem for tin and is not a productive or recognizable English base, so learners cannot reliably derive the meaning 'containing tin' from the form.
Etymology
Stannous comes from the Latin stannum, which means 'tin'. That's why stannous describes a compound that contains tin, and you see it in names like 'stannous fluoride' on some toothpastes.
