The Greek word is πατσούρα (pronounced /patsúra/) or πατσούρω (/patsúro/), plural πατσούρες /patsúres/, of uncertain etymology. It means either an ugly hag (an old slovenly woman, with aged and tired skin) or a woman of loose morals.
«πατσαβούρα» in the Ionian. Used more often for old rag - any derogative ref to woman more secondary usage. This would place origin in, Albanian - pačavure according to the op. However, Triandafyllidis gives Ven. spazzadura - rubbish, as origin.
