  What it means

  Literally “as for what concerns / with regard to,” this phrase is a formal Polish connector meaning “as far as X is concerned” or “regarding X.” It introduces a new topic or shifts the focus of a discussion. While grammatically older-sounding, it remains in active use in written Polish and formal speech.

  Vocabulary

  • co — what (relative pronoun)
  • się tyczy — concerns, pertains to (third-person singular of tyczyć się)
  • tyczyć się — to concern, to pertain to, to relate to (imperfective reflexive)

  Grammar note

  'Co się tyczy' is a fixed relative clause that functions as a conjunction phrase. The verb 'tyczyć się' is reflexive (uses 'się') and is used in the third person. What follows is typically a genitive noun phrase: 'Co się tyczy tej sprawy…' ('As far as this matter is concerned…'). The genitive is required because 'tyczyć się' governs the genitive case.

  Cultural context

  This phrase has a slightly formal, written register. It appears frequently in business correspondence, legal documents, and journalistic prose. In everyday speech, Poles more commonly say 'jeśli chodzi o' ('if it comes to') instead. Using 'co się tyczy' in casual speech can sound humorously stiff.
