Welsh language
There are some sounds and letters that exist in Welsh but not in English, such as the letters and sounds ch and ll. The first sound is pronounced like the Scottish Loch Ness, and one Welsh word that uses it is "bach", which means "small." Ll is a voiceless 'l' and is made by placing the tongue on the top of the top gum, and blowing. A Welsh word that uses the 'll' is "llan", which means "church" and appears often in place names, including one called Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch. Both 'ch' and 'll' are single letters in the Welsh alphabet, along with 'dd,' 'ff,' 'ng,' 'ph,' 'rh,' and 'th.'
