Local tradition derives the toponym from the villagers gouging out the eye of a terrible giant on the opposite mountain with a matsouki 'club' or they drove away the Ottomans who came to plunder the village with clubs. The toponym is derived from the word matsouki meaning a 'stick, club'. The term matsouka is found in medieval Greek and borrowed from the Venetian mazzoca. In Aromanian the forms of the word are mÃÂÃÂÃÂucàand maÃÂucÃÂ, in Romanian maciucàand Albanian macuk/ë, -a, all meaning 'the shepherdâÂÂs staff'. In relation to the village, matsouki refers either to livestock breeders or a once local pseudo-doctor nicknamed Matsoukas, from matsouka 'shepherd's rod' and used in a local phrase 'Matsoukas from the goats became a doctor'.
Linguist Kostas Oikonomou wrote the use of the word in the plural singular in the Aromanian form of the toponym is also valid, Matsouts/-li derived from the plural mÃÂÃÂÃÂuÃÂe of the Aromanian noun mÃÂÃÂÃÂucÃÂ. Oikonomou also states the origin of the locality from the surname Matsoukis cannot be ruled out by transformation into a neuter analogous to the gender of the words village, estate and so on. The surname Matsoukis was formed, as above, the personal name Matsoukas.
Matsouki has an Aromanian population and is an Aromanian speaking village. In the early 21st century, elderly people were bilingual in the community language and Greek, whereas younger residents under 40 might have understood the community language but did not use it.
