button one’s lip To keep quiet or silent; to keep a secret; also button up and button up one’s face or lip. The expression has been in use since 1868.

hugger-mugger Covert or clandestine behavior, secrecy, furtiveness; confusion or disarray. This expression, possibly derived from the Middle English mokeren ‘to conceal,’ appeared in Shakespeare’s Hamlet regarding the manner of Polonius’ burial:

And we have done but greenly In hugger mugger to inter him. (IV,v)

Although the expression maintains its furtive connotation, hugger-mugger now more frequently carries the meaning of jumbled confusion or disorganization, a meaning it assumed because clandestine activity is often hurried and haphazard.

You find matters … so clumsily set out, that you fare in the style called hugger-mugger. (William Jerdan, Autobiography, 1853)

in petto Undisclosed, kept secret; private, in one’s own thoughts or contemplation. This expression is Italian for ‘in the breast.’ Citations dating from the 17th century indicate that in petto is applied almost exclusively to affairs of church or state.

There are seven cardinals still remaining in petto, whose names the Pope keeps secret. (London Gazette, 1712)

little pitchers have big ears An exhortation or reminder to guard one’s tongue because children may overhear words not intended for their ears. The handle of a pitcher is sometimes called its “ear.” Thus, pitchers have ears is a pun on ears, and is analogous in meaning to walls have ears. This expression appeared in print by the mid-1500s; the later addition of little limits the kind of listeners to children.

Surely Miss Gray, knowing that little pitchers have ears, would have corrected the mistake. (Sarah Tytler, Buried Diamonds, 1886)

mum’s the word Remain silent; do not breathe a word of what was just said. Shakespeare conveyed this meaning in Henry VI, Part II:

Seal up your lips, and give no word but—mum. (I, ii)

This expression may have derived from the m-m sound, which can be produced only with closed lips. The phrase is particularly commonplace in Great Britain.

As to Cornwall, … between you and me, Mrs. Harper, mum’s the word. (Dinah Mulock, Agatha’s Husband, 1852)

on the q.t. Secretly, surreptitiously, covertly, clandestinely, on the sly. Q.t. is simply an abbreviation of the word quiet in the original expression on the quiet.

It will be possible to have one spree on the strict q.t. (George Moore, A Mummer’s Wife, 1884)

skeleton in the closet A family secret or scandal kept concealed to avoid public shame and disgrace; any confidential matter which, if revealed, could be a source of embarrassment, humiliation, or abasement. Though popularized in the writings of William Thackeray (1811-63), skeleton in the closet is reputedly based on an earlier legend that tells of a search for a truly happy person, one free from cares and woes. After such a person had apparently been found, she opened a closet and exposed a human skeleton. “I try to keep my troubles to myself,” she explained, “but every night my husband compels me to kiss that skeleton.” The skeleton, it seems, was that of a former paramour whom her husband had killed.

Some particulars regarding the Newcome family … will show us that they have a skeleton or two in their closets. (William Thackeray, The Newcomes, 1855)

A British variation is skeleton in the cupboard.

sub rosa Under the rose—in secret, privately, confidentially. Attempts have been made to trace the origin of this phrase to classical times; however, the OED states that it has Germanic origins. In Germany, and later in England and Holland, it was a common practice to paint or sculpture roses on the ceilings of banquet halls. The rose was a symbol reminding the revelers to watch their words. The phrase appeared in print by the mid-16th century. The English version under the rose is also heard.

Being all under the Rose they had privilege to speak all things with freedom. (James Howell, Parables Reflecting Upon the Times, 1643)

under one’s hat Secret, private, confidential; between you, me, and the lamppost; usually to keep something under one’s hat.

I’d be very grateful … if you’d keep the whole affair under your hat. (N. Marsh, Dead Water, 1963)

Although the exact origin of this expression is not known, perhaps at one time the space under a person’s hat was literally used to conceal things. Use of the phrase dates from the late 19th century.

walls have ears An admonition to be discreet in speech, implying that privacy is never certain and that no one is to be trusted. The expression is often linked with the so-called auriculaires of the Louvre Palace, tubes within the walls by means of which Catherine de Médicis reputedly learned of state secrets. There is no evidence, however, that the phrase actually owes its origin to these contrivances. A similar concept and personification appeared contemporaneously in Heywood’s Proverbs (1562):

Fields have eyes and woods have ears.
