Estonian is the official language of the Republic of Estonia. Compared to other European languages, the Estonian language is one of the smallest with regard to the number of speakers. However, if we take into account that 95% of languages (ca 4,500 languages spoken in the world today) have less than 100,000 speakers, Estonian is a relatively widely spoken language.
