what is generally considered to be an informal,non standard word or expression
Answers
Colloquial terms are considered informal and non-standard expressions.
Slang words are part of colloquial expressions.
These words are commonly used in daily conversations, but are not used when it comes to formal settings. For example, the expression ‘a real good time’ is easily understood by everyone, but is not used in academic essays or formal speeches. The chances of colloquial terms being used by a friend are much greater than hearing them from the head of an educational institution.
Colloquial terms have their own qualities as well. They convey the essence of the region better than other standard words. Therefore, some writers specifically use colloquial terms in their stories and novels to give the readers a flavour of the region, the ethnicity and even the economic class of the people they are portraying in their texts.
