  • Usage note:

    "...leaving them on a broad veranda with a number of domesticated creatures on it, marmosets of three different kinds, an old bald toucan, a row of sleepy parrots, something hairy in the background that might have been a sloth or an anteater or even a doormat but that it farted from time to time, looking around censoriously on each occasion, and a strikingly elegant blue heron that walked in and out."

  • A Brit will blame you for your sloth

    And call for action with an oath.

    But cross the North Atlantic froth

    And hear the Yank condemn your sloth.

    The language is no tailored cloth

    But bubbles like a homemade broth.

    The Web promotes organic growth,

    So Wordnik wisely sanctions both.
