Can i pleeease have ? it's about linking vs verbs.. tell me how to identify which is which

Linking verbs are used to make a connection between a subject and information about the subject. (For example: 1. Atlanta IS the capital of Georgia. - IS connects Atlanta (the subject) to being the capital of Georgia (further information about the subject.)

Helping verbs help the main verb (action) by extending its meaning. (Example- The children WERE playing outside.) Were tells the reader that the children playing outside happened in the past.
