Answer:
Vernacular language is the one spoken by people when they are in an informal context, like they are everyday at home.
Step-by-step explanation:
While Standard English is commonly spoken in formal institutions, like schools and universities or government entities when they want to communicate with people for example, vernacular language is usually spoken by people in an informal context.
An example of Standard English vs vernacular language would be:
Standard English: "I am not going to take care of this situation".
Vernacular language: "I'm not gonna deal with this situation".
Vernacular language makes use of contracted forms and phrasal verbs more widely than Standard English.
