Overview
Please is a word used in the English language to indicate politeness and respect while making a request. Derived from shortening the phrase "if you please" or "if it please(s) you", the term has taken on substantial nuance based on its intonation and the relationship between the persons between whom it is used. In much of the Western world, use of the word is considered proper etiquette, and parents and authority figures often imprint upon children the importance of saying "please" when asking for something from an early age, leading to the description of the term as "the magic word".
Origin and understanding
"Please" is a shortening of the phrase, if you please, an intransitive, ergative form taken from if it please you, which is in turn a calque of the French s'il vous plaît, which replaced pray. The exact time frame of the shortening is unknown, though it has been noted that this form appears not to have been known to William Shakespeare, for whom "please you" is the shortest form used in any of his works. A variation of the phrase, "may it please the court", remains in use as a formality for attorneys addressing judges in legal proceedings. Despite its straightforward definition as a term of courtesy, "please" has become highly variable in its meaning based on its intonation. The use of "please" often reflects an illocutionary act, making its presence in a sentence more a matter of functionality than politeness, but it remains the case that omitting "please" in certain circumstances can be perceived as impoliteness. On a philosophical level, it has been argued that use of "please" embodies the Kantian ethic of treating the person to whom it is spoken as an end, rather than a means, acknowledging them to be inherently worthy of respect.
One study found, however, that using "please" in unusual situations, such as with a seller asking someone to buy something for a charitable cause, yielded a negative result, with customers being less likely to make a purchase when it was used. The researchers theorized that this was because the use of "please" focused the attention of the customer on the seller rather than the cause, and the unusual circumstance of use made the customers suspicious of the interaction.
