What does aspirin mean?
Aspirin is one of the most widely used medicines in the world: an inexpensive, over-the-counter drug whose active ingredient is acetylsalicylic acid. In everyday speech it refers either to the substance itself or to an individual tablet of it, as in 'she took two aspirin'. Its primary uses are relieving headaches, muscle pain, and other minor discomforts, reducing fever, and easing inflammation; at low doses it is also taken regularly under medical guidance because it thins the blood and can lower the risk of heart attack and stroke. The word began as a trademark created by the German company Bayer in 1899, its name echoing spiraea, the plant genus that contains the same active compound long known from willow bark. Over time aspirin became so familiar that it lost its protected status in most countries and entered the language as a plain, uncapitalized noun. It carries no strong emotional connotation beyond associations with home remedies and everyday self-care.
A white, crystalline drug, acetylsalicylic acid, used to relieve pain and fever, reduce inflammation, and prevent blood clotting.
"He keeps a bottle of aspirin in the bathroom cabinet."
Both 'aspirin' (uncountable) and 'aspirins'/'aspirin' (countable, for tablets) are accepted; 'two aspirin' is especially common in American usage.
An individual tablet of this medicine.
"She dissolved two soluble aspirins in a glass of water."
'Aspirins' is the regular plural when counting tablets, though bare 'aspirin' is also widely used as a plural, particularly in American English ('take two aspirin').
"The nurse handed him three aspirins and a cup of water."
Aspirin began life as a brand name coined by the German company Bayer in 1899, inspired by spiraea, the meadowsweet plant that contains the same pain-soothing compound willow bark had been used for since ancient times.

Etymology of aspirin
Aspirin was coined as a trade name by the German pharmaceutical company Bayer in 1899. The name combines elements referencing spiraea (meadowsweet), the plant genus whose salicylic-acid compounds were the chemical ancestor of the drug, with the German suffix '-in' commonly used for pharmaceutical preparations. Salicylates themselves had been isolated from willow bark, long used in folk medicine, during the nineteenth century. Because the word was a brand name rather than an inherited English word, it has no true cognates, though related botanical terms such as 'spiraea' share its linguistic root.
How aspirin is actually used
Aspirin is used both as an uncountable substance ('some aspirin') and countably for tablets ('two aspirins', though 'two aspirin' is also standard, especially in American English). It was originally a trademark owned by Bayer, but after World War I it became genericized in many countries and is now the ordinary word for the drug everywhere except some markets where Bayer still holds rights.
