Sense: noun/1

For sense 1, assertion is stronger than statement because it suggests confidence and insistence. Claim is the nearest everyday word, but it is slightly broader and can sound less formal. Statement is neutral and simply names something said or written. Declaration is more formal and often public or official. Allegation is different because it usually points to an unproved accusation, especially in legal or news contexts. If a scientist writes an assertion that a drug is safe, readers may expect evidence. A police report may include a suspect's claim, but a newspaper is more likely to call it an allegation if wrongdoing is involved.

Etymology

LatinEnglish

Assertion came into English from Latin assertio, a noun from the verb asserere. That Latin verb carried ideas such as claiming, defending, and upholding. Those older ideas still show in modern English, where assertion can mean either a strong claim or the forceful expression of a right or authority.
