analysis: [16] The underlying etymological notion contained in analysis is of ‘undoing’ or ‘loosening’, so that the component parts are separated and revealed. The word comes ultimately from Greek análusis, a derivative of the compound verb analúein ‘undo’, which was formed from the prefix ana- ‘up, back’ and the verb lúein ‘loosen, free’ (related to English less, loose, lose, and loss).

It entered English via medieval Latin, and in the 17th century was anglicized to analyse: ‘The Analyse I gave of the contents of this Verse’, Daniel Rogers, Naaman the Syrian 1642. This did not last long, but it may have provided the impetus for the introduction of the verb analyse, which first appeared around 1600; its later development was supported by French analyser.

patsy (n.)youdaoicibaDictYouDict
"fall guy, victim of a deception," 1903, of uncertain origin, possibly an alteration of Italian pazzo "madman" (see patch (n.2)), or south Italian dialectal paccio "fool." Another theory traces it to Patsy Bolivar, character created by Billy B. Van in an 1890s vaudeville skit who was blamed whenever anything went wrong.
"Poor Rogers," Vincent said, still smiling, "he is always the 'Patsy Bolivar' of the school."
"Yes," Frank answered, "if there are any mistakes to be made or trouble to fall into, Rogers seems to be always the victim." ["Anthony Yorke," "A College Boy," 1899]
