Where it sits
The real origin is slang and only partly understood; the acronym is a 20th-century invention.
What it doesn't mean
The word was in use as a gratuity by 1755, and the acronym story only appears in 1909. Snopes notes it has yet to find an English acronym-word that predates the 20th century.
No such boxes are known. A reviewer in The Athenaeum in 1909 already deplored 'the careless repetition' of this story.
That's part of the story, not the history. As Snopes points out, paying in advance wouldn't 'insure' anything anyway.
What it really means
Tip has one of the best-travelled acronym stories in English. In old English inns, it goes, a box stood by the door marked T.I.P.: To Insure Promptness. Customers who dropped in a coin got faster service, and the box gave its name to the money. Other versions say "To Insure Performance" or "To Insure Prompt Service".
There were no such boxes.
Why it's wrong. The dates run backwards. Etymonline traces tip to thieves' cant around 1600, meaning simply "to give, hand, pass". By 1706 "to tip" meant giving someone a small present of money for service, and the noun tip, a gratuity, is recorded in 1755. The acronym explanation doesn't appear until 1909, in a book about old drinking customs, and a reviewer in The Athenaeum objected immediately to "the careless repetition of popular etymologies". The form "To Insure Promptness" is recorded from 1946.
There's a broader problem too. Words made from initials are a modern habit. Snopes notes it has yet to find an English acronym-word older than the 20th century, while tip is much older than that. Snopes also points out that paying in advance wouldn't "insure" anything: a waiter who has already been paid has less reason to hurry, not more.
What's actually known. The gratuity sense grew out of underworld slang for passing something over. Etymonline suggests a link to tip meaning "to tap", as in tossing someone a coin, though the ultimate origin is uncertain.
This is a classic backronym: an acronym invented to explain a word that was never an acronym at all.
Where it comes from
- c. 1600
Tip means 'give, hand, pass' in thieves' cant, of uncertain origin (Etymonline).
- 1706
The verb 'to tip' means to give a small present of money for service (Etymonline).
- 1755
The noun tip, a gratuity (Etymonline).
- 1909
The acronym tale ('To Insure Promptitude') appears in Frederick W. Hackwood's Inns, Ales and Drinking Customs of Old England — and a reviewer in The Athenaeum objects at once.
- 1946
The 'To Insure Promptness' version of the story is recorded (Etymonline).
In real life
- They left a generous tip because the waiter had remembered their daughter's birthday.
- "Tip stands for 'To Insure Promptness'," said the pub quiz host, and lost a point to the table of linguists.
- In some countries a tip is expected; in others, service is already included in the bill.
Questions
Q01Does tip stand for 'To Insure Promptness'?
No. It's a backronym: an acronym invented after the word. Tip meaning a gratuity is recorded in 1755, while the acronym story first appears in 1909, according to Etymonline.
Q02Where does the word tip come from?
From thieves' cant around 1600, where tip meant 'to give, hand, pass'. By 1706 it meant giving a small sum for service, and the noun followed in 1755. Etymonline suggests it may come from tip meaning 'to tap', as in tossing someone a coin, but the origin is uncertain.
Q03Why is the acronym story wrong?
Because the dates are backwards, and because words formed from initials were very rare before the 20th century — Snopes says it hasn't found one earlier. The story was being criticised as a 'popular etymology' as soon as it appeared in print.
