The first known mention of the word in English was in 1936. The English word is borrowed from Modern Greek πίτα. These all probably come from the Byzantine Greek πίτα 'bread, cake, pie, pitta' (attested in 1108). Some sources trace it to the Ancient Greek πίττα or πίσσα 'pitch/resin', while others characterize this as "unlikely" and trace it to Latin picta 'painted', itself supposedly from Greek πηκτή 'congealed'. Though the Modern Hebrew word pittāh is spelled like the Aramaicpittəṭā/pittā (which is related to Levantine Arabicfatteh), they are not connected historically. Other hypotheses trace it to Germanic or Illyrian.
The word has been borrowed by Turkish as pide, and appears in the Balkan languages as Serbo-Croatianpita, Romanianpită, Albanianpite, Bulgarianpitka. In Arabic, the phrase "خبز البيتا" (pita bread) is sometimes used; other names are simply "خبز" 'bread' or "الخبز العربي" 'Arab bread'.
Most pita are baked at high temperatures (450 °F or 232 °C), causing the flattened rounds of dough to puff up dramatically. When removed from the oven, the layers of baked dough remain separated inside the deflated pita, which allows the bread to be opened to form a pocket. However, pita is sometimes baked without pockets and is called "pocket-less pita".
Nowadays, modern commercial pita bread is prepared on advanced automatic lines. These lines have high production capacities ranging from a few hundreds per hour up to thousands per hour.
In Greece, pita is a component of pita-souvlaki. These types of sandwiches involve the wrapping of souvlaki or gyros with tzatziki, tomatoes, onions, french fries, hamburgers, and condiments into a pita bread. Also, several pitas are found all over Greece (as a home meal or as appetizers, snacks or desserts), such as Kolokythopita, Mizithropita (Crete), Melintzanopita, Tsouknidopita, Kremydopita, Kreatopita (meat pie), Galatopita, Marathopita, Tyropita, Spanakopita, Malathropita (Chios), Ladopita.
In Cyprus, pita is typically rounder, fluffier and baked on a cast iron skillet. Used for Souvlakia, Sheftalia, Halloumi lountza, and gyros.
In Turkish cuisine, the word pide may refer to three different styles of bread: to a flatbread similar to that eaten in Greece and Arab countries, to a pizza-like dish where the filling is placed on the (often boat-shaped) dough before baking, and to Ramazan pide. The first type of pide is used to wrap various styles of kebab, while the second is topped with cheese, ground meat or other fresh or cured meats, and/or vegetables. Regional variations in the shape, baking technique, and toppings create distinctive styles for each region.
