Here's a quick summary of the different kinds of words we have in the English language and what they are used for.

Dates are usually expressed with ordinal numbers. Sometimes, though, what we write is different from what we say.

Ordinal numbers help us put things in order or in a sequence. Sigrid teaches us the suffixes we use to turn cardinal numbers into ordinal ones.

Sigrid explains what cardinal numbers are and gives us some writing and pronunciation tips.

Sigrid finishes the alphabet with "Z," covering words like "zone" and "zebra," but also the useful suffix "-ize."

"Y" is a tricky letter because it's both a consonant and a vowel. As a vowel, it has different sounds. Don't worry. But hey, maybe keep your eye on the "Y." Don't let it fly away.

"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.
