- Identify conjunctions, prepositions, and interjections in sentences and explain their function
- Explain how removing a preposition or conjunction changes the meaning of a sentence
- Use interjections appropriately to convey emotion in dialogue or informal writing

## Lesson: Little Words That Do Big Jobs

You already know that prepositions show time, place, or cause, like 'before the race' or 'because of the fog'. Two more small words do big jobs in a sentence: conjunctions join ideas together, and interjections burst out a feeling on their own.

*(drawing: The word 'because' joins two ideas: staying inside, and the rain outside.)*

**Example.** Look at 'The keys are under the mat.' Now take away 'under': 'The keys are the mat.' The sentence breaks, because the preposition was showing exactly where the keys are.

An interjection is a short word or phrase that shows sudden feeling, like 'wow', 'ouch', or 'oh no'. It doesn't join to the rest of the sentence. Writers set it apart with a comma or an exclamation mark, especially in dialogue.

**Tip.** Here's a quick way to sort them: a preposition links a noun to time, place, or cause. A conjunction links two ideas or clauses. An interjection stands alone and shows feeling.

**Recap.** Conjunctions join ideas, prepositions link nouns to time, place, or cause, and interjections burst out feeling on their own.
