ENQuestions regarding the viability of the national language are inevitably entwined in the national educational policy, social trends, and attitudes towards the use of languages. This article showcases the data from a study of the use of language and language attitudes of Lithuanian pupils aged 10 to 14 that was conducted in 2018–2019. The article looks into the languages that dominate the pupils’ vernacular, the pupils’ attitudes towards the relationship between the Lithuanian language and identity, the prestige of the language, and the language’s creative potential. The data from the study have revealed that, depending on the field, the daily vernacular of the pupils is dominated by two languages: Lithuanian and English. A majority of the pupils say they speak Lithuanian at home, and nearly all of them read Lithuanian books; however, on social media and in daily vernacular Lithuanian is used in tandem with English. Most of the pupils say they consider the ability to speak Lithuanian a part of their identity, yet only half of the pupils believe it to be irreplaceable, the language that expresses their feelings and ideas the best. Only slightly more than half of the pupils consider Lithuanian a modern language, while only one-third believe its resources need to be enlarged.Examining results in different cities, Šiauliai pupils tend to have weaker attitudes towards their Lithuanian language identity, more often than elsewhere preferring English, considering English a language with a higher degree of prestige. Klaipėda pupils stand out in their strong linguistic and national self-identity. Pupils in Panevėžys choose Lithuanian over other languages more often than pupils in any other city. Contrary to what might be expected, the attitudes that pupils in the multicultural capital city have towards their identity and the social value of the Lithuanian language is similar to those of pupils from other cities. Vilnius has the lowest number of pupils who believe that Lithuanian is a dated language. The results point to differences of opinion on languagerelated topics across Lithuanian regions, though the overarching trends are similar: a strong personal relation with the Lithuanian language and little confidence in its creative potential.
