"Is my son here, Clarence?" asked Roger Oakley. "Nope. The whistle ain't blowed yet."

"No," from Tom, ending the word with so decided a pressure of the lips that it sounded like "nope."

“Aunt Kat? And was Aunt Kat your only relation? Have you no father nor mother?” “Nope. Never had none ‘cept Aunt Kat. Her hull name was Katrina. She wuz Dutch she wuz."

1: I will not dishonour my country's speech by leaving off the last syllables of words, 2: I will say a good American "yes" and "no" in place of an Indian grunt "um-hum" and "nup-um" or a foreign "ya" or "yeh" and "nope"...

Nope. Don't know as I do.

I noped out of there as quickly as possible.

Ill take that as a nope, then.''

This cemetery with a haunted playground is a casket full of nope.

To Philomell the next, the Linnet we prefer;/And by that warbling bird, the Wood-Lark place we then, /The Reed-sparrow, the Nope, the Red-breast, and the Wren, /The Yellow-pate: which though she hurt the blooming tree, /Yet scarce hath any bird a finer pipe than she.

I may note that olp, if pronounced ope, as it sometimes is, may be the origin of nope; an ope, and a nope, differ as little as possible.

In Natural History, 'An Eye of Pheasants' was also 'A Nye of Pheasants', and even the human Eye was written a Nye. The Bulfinch was either a Nope, or an Ope ; the common Lizard, or Eft (Old English Evet) is also the Newt; the Water-Eft is the Water-Newt ; and the Saxon nedder, a serpent (probably allied to Nether, as crawling on the ground) has been transformed into an Adder.

Nope, an old name for the bullfinch used by Drayton (Wright), is a corrupt form for an ope, otherwise spelt aupe, olp, or alpe (Prompt.Parv.).

(in an example of use of crackmans) The cull thought to have loped by breaking through the crackmans, but we fetched him back by a nope on the costard, which stopped his jaw.

I'll fetch thee a nope.

"Nope him on the costard," said Ben Bolter.

The sexton seemed reluctant to resume his old duties, remarking -- "Be I to nope Mr. M on the head if I catches him asleep?"
