Morphology
heptane = hept + ane
Formed from the Greek combining form 'hept-' (seven) + the specialised chemical suffix '-ane'; this nomenclature is domain-specific and not transparently meaningful to an average B1 learner.
Etymology
Heptane comes from the Greek part hepta meaning 'seven' and the chemical ending -ane, because the molecule has seven carbon atoms. So the name tells you how many carbons it has, which helps chemists understand its properties.
