Question

What is/are the noun(s) in the following sentence?: The cars were stuck in a traffic jam because the traffic lights were broken.

Answer 1

See below.

Explanation:

A noun is a person, place, or thing. Something you can smell, hear, taste, touch, and see.

In this sentence:

The cars were stuck in a traffic jam because the traffic lights were broken.

.. The nouns are:

Cars
Traffic
Lights
Jam

You can see, hear, smell, touch, and taste (although I wouldn't recommend it) a car.

You can see traffic, touch it, smell it, hear it, and taste it.

Lights can be seen, heard, smelled, tasted, and touched.

A jam can be seen, smelled, tasted, and touched.

If you can do this to something, then it is a noun.

Hope it helped (:

Answer 2

cars, jam, lights.

Explanation:

cars because this is the subject of the sentence.
jam because this is the object of a prepositional phrase.
lights because this is the subject of the second phrase

traffic by itself is a noun however in this sentence it is being used as an adjective in both cases. traffic describes what kind of jam and what kind of lights are being referred to.
