1.2 Grammar .
Language, no matter what it is standard or nonstandard, must express itself according to some grammar rules. Slang is a kind of extremely nonstandard spoken speech, but it has a set of unique grammar characteristics, which materialize the aspects as follows. .
1.2 Adjective comparative degree and superlative degree using "dualism", e.g., .
a more larger list of scepters (Anthony and Cleopatra, 676) £ »the most worst winter (Winter Tale,
•o,2,180)etc. .
1.2.1 Anomalistic verb past voice +ed in the end of words, e.g., .
comed (came),seed(saw), knowed (knew)etc. .
1.2.2 Past participles and verbs in past tense are used interchangeably: .
(1) I seen him walk up. (=I saw him walk up). .
(2) He gone out last night. (= He went out last night) .
(3) I saw him go. (=I have seen him go) .
1.2.3 Over-extensive use of the third singular single: .
(4) I goes and lends that (= I go and lend that) .
(5) They haves a house (= They have a house) .
Furthermore, both of the negatives of the first and second personal pronoun (single and plural) use ain't; the second personal single verb be uses was; the third personal single of verb present voice usesest etc. .
The above slang grammar characteristics apparently run counter to standard grammar. Slang, however, does not care much about the grammar logical relation and pragmatics formula. The purpose of such use is to achieve relaxation and casualness through humorous expressions. .
1.3 Vocabulary .
