Other forms: portfolios
A portfolio is a large, flat briefcase used to hold papers and other loose materials, like maps or artwork. A portfolio is usually used to transport important documents, like examples of your graphic design work if you’re an artist.
The noun portfolio has its roots in the similarly-sounding Latin portafoglio “a case for carrying loose papers.” Notice, within that word, two other words — there’s porta, meaning “carry,” and foglio, meaning “sheet, leaf.” In English, think portable folio, or papers that can be carried. Also, portfolio can refer to the duties of a government official or the collection of investments held by a financial company.
