Collective nouns

Sometimes we talk about many things of one kind together: many sheep, many bees, many keys. English has special words for such groups. They are called collective nouns.

On pages 3 and 4 of your book, Santoor, you name groups from pictures, using the words in a box. The book does the first one for you: a bundle of sticks. A bundle is many sticks tied together.

Here are more groups from your book. A herd of sheep: many sheep together in a field. A pack of wolves: wolves that live and hunt together. A bouquet of flowers: flowers tied together, often to give as a gift. A grove of trees: a small group of trees growing together. A swarm of bees: many bees flying together, often round their hive. A bunch of keys: keys held together on one ring.

The box on page 3 also has the word 'choir'. A choir is a group of people who sing together.

Notice the little word 'of' in each one: a swarm OF bees, a bunch OF keys. The group word comes first, then 'of', then the things in the group.
