Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid direct translation with 'гипотетизировать' (extremely rare/awkward). Use 'выдвигать гипотезу', 'предполагать', or 'строить догадки' depending on context.
  • Confusing 'hypothesize' with 'assume' (предполагать без доказательств). 'Hypothesize' implies a testable proposition.

Common Mistakes

  • Incorrect: 'I hypothesize you are tired.' (Correct: 'I hypothesize that you are tired.')
  • Misspelling: 'hypothesisize' (extra 'is').

Yes, but less commonly. E.g., 'The article hypothesizes a novel mechanism for the disease.' The 'hypothesize that...' pattern is more frequent.
