- 1A metallic salt of a fatty acid, used in many cleaning products.
Traditional soap forms when animal fat reacts with sodium hydroxide.
Hard water can make soap less effective at cleaning.
Note
The chemist's soap is a precise thing: usually a sodium or potassium salt, made by saponification, in which a fat reacts with an alkali and leaves glycerol behind. The word itself is old. Old English sāpe meant both "soap" and "salve." The strict sense draws a line that everyday speech ignores, since the broader cleaning sense happily covers detergents that are not soaps at all.
- 2To apply soap to something in the process of washing it.
He soaped the car thoroughly before hosing it down.
Always soap your hands for at least twenty seconds.

- 4To cover or smear something with soap, often as a prank.
Teenagers soaped the school windows the night before graduation.
They threatened to soap every window on the street.
- 5A detergent or other surfactant able to mix with both oil and water, used for cleaning, even when it is not a true soap.
Most bathroom soap today is actually a synthetic detergent rather than a true fatty-acid salt.
A few drops of soap let the water spread across the greasy surface.
Note
Everyday speech stretches the word to any cleaner that behaves the way soap does. What qualifies is the molecule's double nature: one end clings to oil and the other to water. This lowers surface tension and lifts grease into suspension so it rinses away. Much of what is sold and asked for as soap is really a synthetic detergent, and outside a lab nobody minds.
- 6Money, especially money used as a bribe.
A bit of soap in the right pocket got the permit approved overnight.
He claimed the official wouldn't move without some soap changing hands.
Note
Slang that pictures a bribe as a lubricant: money that lets an awkward deal slide through. It usually works as a mass noun (some soap, a bit of soap) and belongs in knowing talk about graft rather than neutral writing. There, bribe or payoff says the same thing without the wink.
- 7A brick or masonry unit made shallower or shorter than the standard size.
The mason cut a soap to finish the course neatly against the window frame.
Builders order soaps when a wall needs a thinner finishing course.
- 8To keep a topic quiet and avoid discussing it openly.

- 9Thiopental sodium, a fast-acting barbiturate used in anesthesia and popularly regarded as a truth serum.
Interrogators in the thriller injected the captive with soap.
She joked that only a dose of soap would get him to confess.
Note
This is an unrelated word that only looks like the cleaning one. It is probably a clipping of sodium pentothal. John Gardner's James Bond novels call it intelligence speak, and it belongs to the world of interrogation: a shot of soap given to make a captive talk. Its fame as a truth serum is far stronger than the pharmacology behind it.
Less common meaning
- 10To flatter or coax someone with smooth talk, usually to gain an advantage.
He tried to soap the magistrate with extravagant compliments.
She soaped her wealthy aunt at every visit, angling for a spot in the will.
Similarflatter, cajole, coax, wheedle, sweet-talk
Note
Where the slang for a bribe greases a deal with money, this dated sense does it with words. It takes the person as its object: you soap a magistrate or a wealthy aunt. Today it has a period flavor. Flatter or wheedle is the safe choice in current speech, and soap suits historical settings or a deliberately old-fashioned voice.

Origins
From Middle English "sope," from Old English "sāpe" (soap, salve), going back through Proto-Germanic to a Proto-Indo-European root meaning "to pour out, drip, trickle." It is related to Dutch "zeep," German "Seife," and Swedish "såpa," and the Latin word "sāpō" was actually borrowed from Germanic.
This sense is probably an abbreviation of "sodium pentothal."
