Estonian is considered the 5th most challenging language for native English-speakers to learn, yet sounds whimsical and fairytale-like. Only approximately 1.1 million people in the world speak this extraordinary language. The Estonian Institute asked foreigners studying Estonian their opinions about the language. Their responses indicate that the most beautiful Estonian words are lauluhääl, laulupidu and lauluväljak (all referring to singing and song), while the strangest words are küsimusi, jäääär and loll. The word öö, meaning night, belonged to both lists, making it one of the most lovely and peculiar words.
The World Health Organization has ranked Estonia's air as some of the cleanest air in the world, along with countries like Finland and Iceland. The fact that over half of Estonia's land area is covered by forest (52%), making it the 6th most forested nation in Europe, contributes to the pure air quality. Nature reserves make up about one fifth of Estonia's wilderness, ensuring preservation for the future.
