Name of Poland

The ethnonyms for the Poles (people)and Poland (their country) include endonyms (the way Polish people refer to themselves and their country) and exonyms (the way other peoples refer to the Poles and their country). Endonyms and most exonyms for Poles and Poland derive from the name of the West Slavic tribe of Polans (Polanie), while in some languages the exonyms for Poland derive from the name of another tribe – the Lendians (Lędzianie).

The Polish words for a Pole are Polak (masculine) and Polka (feminine), Polki being the plural form for two or more women and Polacy being the plural form for the rest. The adjective "Polish" translates to Polish as polski (masculine), polska (feminine) and polskie (neuter). The common Polish name for Poland is Polska. The latter Polish word is an adjectival form which has developed into a substantive noun, most probably originating in the phrase polska ziemia, meaning "Polish land".

The full official name of the Polish state is Rzeczpospolita Polska which loosely translates as "Republic of Poland". The word rzeczpospolita has been used in Poland since at least the 16th century, originally a generic term to denote any state with a republican or similar form of government. Today, however, the word is used almost solely in reference to the Polish State. Any other republic is referred to as republika in modern Polish.

It is sometimes assumed that all of the above names derive from the name of the Polans (Polanie), a West Slavic tribe which inhabited the territories of present-day Poland in the 9th-10th centuries. The origin of the name Polanie itself is uncertain and the earliest references to it appear among East Slavs in the area around the Dnieper River. It may derive from the word pole, Polish for "field".
