Nouns are usually the first words we learn. The good news is that with nouns, we don't have to worry about gender in English. We do, however, have to be aware of gerunds that act like nouns but look like verbs, and countable or uncountable nouns.

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.

Do you want to prepare for that big job interview? If so, take a look. Gabrielle offers some valuable information and a few helpful hints.

"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.
