Explanation:
Linking verbs are those words that help link the subject to the information about the subject. Linking verbs may or may not necessarily be actions but will act as the link between the subject and the information.
1. I <u><em>am</em></u> happy to help the frontliners by simply staying indoors.
In this sentence, "am" connects the subject "I" to the detail about the subject even though the word by itself is not an action word.
2. I <u><em>disagree</em></u> that parents should not limit their children's use of gadgets.
In this sentence, "disagree" is the linking verb as it links the subject with the information. Moreover, it also has a dual 'identity' as it is also an action word.
Modal verbs are those words such as "should, might, would, can" etc. These words indicate the possibility, the modality of the sentence.
