Latvian language
Latvian ("Latviešu valoda" ) is a Baltic language spoken in the Baltic region. It is the language of Latvians and the official language of Latvia as well as one of the official languages of the European Union. It is sometimes known in English as Lettish, and cognates of the word remain the most commonly used name for the Latvian language in Germanic languages other than English. There are about 1.3 million native Latvian speakers in Latvia and 100,000 abroad. Altogether, 2 million, or 80% of the population of Latvia, speak Latvian. Of those, 1.16 million or 56% use it as their primary language at home. The use of the Latvian language in various areas of social life in Latvia is increasing.
Pitch-accent language
Two languages of the Baltic branch of the Indo-European family survive today, namely Lithuanian and Latvian. (Another Baltic language, Old Prussian, died out in the 18th century.) Both languages have a tonal accent that is believed to derive from the ancestral Proto-Indo-European language.
Baltic tones are often classified as either "acute" or "circumflex." However, these labels indicate a diachronic correspondence rather than a phonetic one. For example, the "acute" accent is falling in Lithuanian but a high level tone in Latvian and is presumed to have been rising in Old Prussian and Classical Greek. The "circumflex" is rising in Lithuanian but falling in Latvian, Prussian and Classical Greek.
