Confusing Words

however vs nevertheless / nonetheless

However, nevertheless, and nonetheless all signal contrast or concession in formal writing, but they differ in strength and formality.

  • however — However introduces a contrast and is the most common choice in school and academic writing: 'The plan is promising; however, it needs more evidence.'
  • nevertheless — Nevertheless means 'even so'. It acknowledges a difficulty but shows that the main point still stands: 'The evidence is limited; nevertheless, the findings are useful.'
  • nonetheless — Nonetheless has a very similar meaning to nevertheless and is also formal: 'The policy is expensive; nonetheless, it may produce long-term benefits.'

Memory rule: A helpful rule: use however for normal contrast. Use nevertheless or nonetheless when you want to say 'even with that problem, this point still matters'.
