Etymology
The term 'Lithuanian' is a demonym formed by adding the English adjectival suffix '-ian' to the country name 'Lithuania'. The name 'Lithuania' first appears in Latin chronicles from the 11th century as 'Litua' or 'Lithwania', likely borrowed from an Old Slavic form. This Slavic name is thought to derive from the name of the Lietava River in central Lithuania, itself possibly originating from the Old Slavic root meaning 'to flow' or 'to pour'. Thus, the modern identity label 'Lithuanian' carries the ancient geographical logic of "the people from the land of the flowing river."
Analysis
The word is a proper name derived from the country name "Lithuania". It is not productively formed from smaller, free morphemes in modern English. The base "Lithuania" itself originates from the Old Slavic name for the region.
Examples
