"X" is a special letter in that we often use it by itself. It's useful in a lot of situations. In the middle of a word, however, it can be pronounced in a few different ways.

"W" is a consonant, but it is very vowel-like and is considered a "semi-vowel." "W" is featured in plenty of important words, and it combines with other letters to make some new sounds.

"V" is a voiced consonant. "Voice" starts with "V." We make the sound with the upper teeth lightly touching the lower lip, like "F" but with the voice, too. It vibrates. The verb "to vibrate" also starts with "V." That should make it easy to remember.

"U" is an interesting vowel, and has a few different sounds. It can even sound like the consonant "Y," and combines with other vowels to make new sounds.

"T" is for "tricky." Depending on what letters "T" is combined with or next to, it is pronounced differently. Sigrid explains and gives some examples.

The letter "S" has a couple of different sounds. It's a very important letter because it's used to form the plural of many nouns as well as the third person singular of verbs.

The letter "R" is difficult to pronounce for lots of people, even native speakers. Sigrid shows us how "R" sounds in different kinds of words.
