Answer:
The verb is 'chase'
Step-by-step explanation:
A verb is a word used to describe an action, state, or occurrence and it forms the main part of the predicate. There are around 7 types of verbs (there may be more types) which are action verbs, stative verbs, transitive verbs, intransitive verbs, linking verbs, helping verbs (the more formal name for these taught at school later on would be auxiliary verbs), modal verbs and lastly regular verbs!
How to indentify/find a verb:
Verbs always tell the time (also called the tense if your smart lol) of the sentence. The easiest way to find a verb in a sentence is to change the time of the sentence and find the word that changes. For example, take the sentence 'Sam was running.' That sentence is in present tense so let's change it too past tense. Now, the sentence would be 'Sam ran.' Now, what word changed? The word running changed to run- and that is the verb in the sentence. (I know that the word 'was' removed from the sentence but let's ignore that lol) Personally, I don't use that method- I feel like identifying verbs just comes naturally to me so I just see the word. Not sure how to explain it ;-;
