Usage Note

Commonly modifies comparative adjectives (e.g. better, cheaper, faster) and past participles (e.g. improved, reduced). More formal than the near-synonym 'slightly'; best suited for written reports, evaluations, and data analysis rather than casual conversation.

Common Mistakes

The price is marginal better.
The price is marginally better.
the adverb 'marginally' is needed to modify the adjective 'better', not the adjective 'marginal'.
Sales marginal increased.
Sales increased marginally.
'marginally' must come before the adjective or after the verb it modifies; it cannot replace the adjective form.

Synonym discussion

Sense: adverb/1

All four words express a small degree or amount, but they differ in register and precision. 'Slightly' is the most neutral and versatile — 'The door was slightly open' works in any context. 'Marginally' is more formal and implies a difference so tiny it sits at the very edge of measurement — 'Profits rose marginally' suggests a bare, almost borderline increase. 'Somewhat' is vaguer and often hedges a claim — 'I am somewhat tired' avoids fully admitting it. 'A little' is informal and everyday — 'Can you speak a little louder?' would sound odd in a formal report. Of the four, 'marginally' appears least in conversation and most in written evaluations, business reports, and scientific comparisons.

Etymology

LatinFrenchEnglish

Comes from the noun 'margin' (the edge or border of something) plus the adverbial suffix '-ally'. The word 'margin' traces back through French 'marge' to Latin 'margo' meaning 'edge'. Over time, 'marginal' shifted from 'at the edge' to 'barely within the limit', and 'marginally' came to mean 'by an amount at the very edge of being noticeable'.
