Something to chew on:
THE NOTION OF STANDARD SPOKEN GRAMMAR
The term ‘standard grammar’ is most typically associated with written language,
and is usually considered to be characteristic of the recurrent usage of adult,
educated native speakers of a language. Standard grammar ideally reveals no
particular regional bias. Thus ‘Standard British English’ grammar consists of items
and forms that are found in the written usage of adult educated native speakers
from Wales, Scotland and England and those Northern Irish users who consider
themselves part of the British English speech community.
The typical sources of evidence for standard usage are literary texts, quality
journalism, academic and professional writing, etc. Standard grammar is given the
status of the official record of educated usage by being written down in grammar
books and taught in schools and universities.
Spoken transcripts often have frequent occurrences of items and structures
considered incorrect according to the norms of standard written English. However,
many such forms are frequently and routinely used by adult, educated native speakers.
Examples of such structures are split infinitives (e.g. We decided to immediately sell it),
double negation (e.g. He won’t be late I don’t think, as compared to I don’t think he will
be late), singular nouns after plural measurement expressions (e.g. He’s about six foot
tall), the use of contracted forms such as gonna (going to), wanna (want to), and so on.
Standard spoken English grammar will therefore be different from standard
written English grammar in many respects if we consider ‘standard’ to be a
description of the recurrent spoken usage of adult native speakers. What may be
considered ‘non-standard’ in writing may well be ‘standard’ in speech.
Speech and writing are not independent. Although some forms of spoken
grammar do not appear in writing (unless in written dialogues), there is
considerable overlap and there is an increasing range of forms appearing in
informal written texts which previously were only considered acceptable in
speech. In 120 the presence of typically spoken grammatical forms contexts as emails and internet chat-room exchanges is discussed.
