Scottish ministers have said they want to encourage more people to learn a second language.
Publishing a consultation on a new language strategy, culture minister Patricia Ferguson said the diversity of languages spoken across Scotland should be recognised.
But she added it was time to develop a "coherent approach" to the languages in use across the country.
It is estimated that about 150 languages in addition to English are in use in Scotland.
The strategy seeks to cover issues from language learning in schools to training British Sign Language translators.
It emphasises the need to equip all Scots with fluent English language skills, as well as promoting linguistic diversity and multilingualism including BSL and ethnic community languages.
The document also proposes the protection and promotion of the Gaelic language.
"It is important for Scottish public bodies to ensure that Scots is recognised as a valid means of communication and cultural expression," it adds.
Ferguson said: "This strategy seeks to provide a coherent approach to guide the development of languages in Scotland and to complement and encourage the progress that has been made so far."
"Through this strategy we aim to raise the profile of the rich and diverse languages spoken in Scotland, to ensure that this rich heritage is recognised as a national resource and to encourage people living in Scotland to learn languages other than their own."
