Morphology
nitrous = nitre (opaque) = nitr + ous
Although the word is historically related to 'nitre' plus the adjective-forming suffix '-ous', its modern chemical meaning is specialized and not readily inferable for most learners from that base alone.
Etymology
Nitrous comes from the old word nitre, which means 'saltpetre', and the ending -ous means 'full of'. So nitrous literally means 'full of nitrogen', which is why we use it for substances or gases that contain nitrogen, such as compounds in fertilizers or the gas used in medicine.
