The meaning is directly derived from 'four' plus the productive suffix '-fold' meaning 'times' or 'having parts', so learners can infer 'having four parts' or 'four times'.

Etymology

Fourfold comes from joining the number four and fold, an old word for 'layers' or 'times'. So something described as fourfold has four parts or is four times as much. A helpful way to remember it is to imagine folding paper twice to make four layers.
