Shakespeare sort of made up a language in All's Well That Ends Well. It is only in two scenes and is used as part of a trick being played. The participants in the trick are given the following guidance:
First Lord:
He must think us some band of strangers i' the
adversary's entertainment. Now he hath a smack of
all neighbouring languages; therefore we must every
one be a man of his own fancy, not to know what we
speak one to another; so we seem to know, is to
know straight our purpose: choughs' language,
gabble enough, and good enough. As for you,
interpreter, you must seem very politic.
Act IV sc i:
Second Lord: Throca movousus, cargo, cargo, cargo.
All: Cargo, cargo, cargo, villiando par corbo, cargo.
PAROLLES: O, ransom, ransom! do not hide mine eyes.
They seize and blindfold him
First Soldier: Boskos thromuldo boskos.
PAROLLES: I know you are the Muskos' regiment:
And I shall lose my life for want of language;
If there be here German, or Dane, low Dutch,
Italian, or French, let him speak to me; I'll
Discover that which shall undo the Florentine.
First Soldier: Boskos vauvado: I understand thee, and can speak
thy tongue. Kerely bonto, sir, betake thee to thy
faith, for seventeen poniards are at thy bosom.
PAROLLES: O!
First Soldier: O, pray, pray, pray! Manka revania dulche.
Second Lord: Oscorbidulchos volivorco.
First Soldier: The general is content to spare thee yet;
And, hoodwink'd as thou art, will lead thee on
To gather from thee: haply thou mayst inform
Something to save thy life.
PAROLLES: O, let me live!
And all the secrets of our camp I'll show,
Their force, their purposes; nay, I'll speak that
Which you will wonder at.
First Soldier: But wilt thou faithfully?
PAROLLES: If I do not, damn me.
First Soldier: Acordo linta.
Come on; thou art granted space.
Exit, with PAROLLES guarded.
And again in in Act IV sc ii:
First Lord: Hoodman comes! Portotartarosa
First Soldier: He calls for the tortures: what will you say
without 'em?
PAROLLES: I will confess what I know without constraint: if
ye pinch me like a pasty, I can say no more.
First Soldier: Bosko chimurcho.
First Lord: Boblibindo chicurmurco.
