Contractions of the verb "to be"
The verb "to be" is often contracted in the present tense when it occurs after pronouns and nouns. The contraction for the third person may be confused with a possessive. For example, the sentence "The boat's sinking" means "The boat is sinking" and the contraction "'s" is part of the verb phrase "is sinking". However, in a sentence such as "The boat's sinking was a tragedy", the word "boat's" is a possessive form and not a contraction. In this case, "sinking" is a gerund (a present participle verb form used as a noun) and not part of a verb phrase. The contraction "it's" is frequently confused with the possessive pronoun "its".
|he's, she's, it's||he is, she is, it is|
Negative contractions are formed by appending "n't" to the present and past forms of the verb "to be", as illustrated here:
The word "ain't"
"Ain't" was originally derived from the negative contraction of "am not", but in the 19th century it began being used indiscriminately for "is not" and "are not" disregarding person agreement. This misuse associated a stigma with the word "ain't" so that now it is considered substandard or slang. "Ain't" is generally used by people who are illiterate, ignorant, and uneducated. It is not unusual to hear "you ain't", "they ain't", "he ain't", etc., but it is considered wrong, wrong, wrong! If you want to succeed in life, don't use the word "ain't".
William Shakespeare - To be, or not to be (from Hamlet 3/1)
To be, or not to be: that is the question: Whether 'tis nobler in the mind to suffer The slings and arrows of outrageous fortune, Or to take arms against a sea of troubles, And by opposing end them? To die: to sleep; No more; and by a sleep to say we end The heart-ache and the thousand natural shocks That flesh is heir to, 'tis a consummation Devoutly to be wish'd. To die, to sleep; To sleep: perchance to dream: ay, there's the rub; For in that sleep of death what dreams may come When we have shuffled off this mortal coil, Must give us pause: there's the respect That makes calamity of so long life; For who would bear the whips and scorns of time, The oppressor's wrong, the proud man's contumely, The pangs of despised love, the law's delay, The insolence of office and the spurns That patient merit of the unworthy takes, When he himself might his quietus make With a bare bodkin? who would fardels bear, To grunt and sweat under a weary life, But that the dread of something after death, The undiscover'd country from whose bourn No traveller returns, puzzles the will And makes us rather bear those ills we have Than fly to others that we know not of? Thus conscience does make cowards of us all; And thus the native hue of resolution Is sicklied o'er with the pale cast of thought, And enterprises of great pith and moment With this regard their currents turn awry, And lose the name of action. - Soft you now! The fair Ophelia! Nymph, in thy orisons Be all my sins remember'd.
