- Spot a dangling modifier in a sentence and rewrite it to remove the ambiguity

## Lesson: How Phrases and Clauses Build a Sentence

You already know how expanded noun phrases describe things and how prepositional phrases add detail about where or when, like on the mat. Now zoom out: every sentence is built from phrases and clauses working together. A clause is built around a verb and has its own subject. A phrase is a group of words acting as one unit, but it can't make a full point by itself.

*(drawing: "Before the game started" is a subordinate clause: it can't stand alone. "We warmed up" is the main clause: it makes sense by itself.)*

**Example.** "The cat slept on the mat." "On the mat" is a prepositional phrase: it starts with the preposition on and ends with the noun mat. It tells you where the cat slept, so it acts as an adverbial, describing the verb slept.

**Example.** "Walking home from school, the rain soaked her backpack." This sounds like the rain was walking home, which makes no sense. The describing phrase "walking home from school" needs to sit next to the person doing the walking. Fix it: "Walking home from school, she got soaked by the rain."

**Tip.** To catch a dangling modifier, check the word right after the comma. Ask: is that who or what is actually doing the action described in the phrase? If not, rewrite the sentence so it is.

**Recap.** Clauses have their own subject and verb, phrases work as one unit but don't stand alone, and a describing phrase must sit right next to the thing it describes.
