についてConcerning, About, Regarding

について is a combination of the case marking particle に, the verb う - Verb 就(つ)く 'to assume a position', and the conjunction particle て. It is most often translated as 'about (A)', or 'concerning (A)', with the literal translation being closer to 'taking the position of (A)', or 'assuming the topic of (A)'.

について may be used after nouns, or noun-phrases (phrases that use こと, の, etc).

について may also appear before の + noun. In this use, it means '(A) that is about (B)'.

Caution

It is rare to see について actually using the kanji 就(つ). について itself is regularly considered as a single compound word, rather than a combination of its parts.
