Synonym discussion

Sense: noun/2

All five words describe making something better by adding to it, but they differ in register and scope. 'Addition' is the most general and informal — you can add salt to a recipe or add a name to a list. 'Supplementation' is formal and implies that the original thing is incomplete or insufficient; it often carries the idea of filling a specific gap (e.g., income supplementation). 'Augmentation' focuses on increasing size or amount, often in technical or military contexts (e.g., troop augmentation). 'Enhancement' is about improving quality or value rather than size (e.g., software enhancement). 'Enrichment' has a positive, qualitative flavour and is common in education (curriculum enrichment) and nutrition (food enrichment). Choosing the right word depends on whether the focus is on quantity (augmentation), quality (enhancement), completeness (supplementation), or general addition.

Etymology

LatinFrenchEnglish

From Latin 'supplementum' meaning 'something added to fill up,' derived from 'supplere' (to fill up, complete) — formed from 'sub-' (from below, up from under) and 'plere' (to fill). English borrowed 'supplement' in the late 1300s; 'supplementation' emerged later to describe the process or practice of adding supplements, especially in medical and financial contexts.
