Reanalysis is a new analysis of something. It may refer to:

• Reanalysis (linguistics) or folk etymology, change in a word or phrase resulting from the replacement of an unfamiliar form by a more familiar one
  • Rebracketing, a process where a word originally derived from one source is broken down into a different set of factors
  • Back-formation, a process of creating a new word by removing actual or supposed affixes
• New statistical analysis of a data set that has already been analyzed
• A repeat analysis, for example in chemistry
