Pronunciation: [stˈe͡ɪn] (IPA) 
The word "stain" is spelled with the letters s-t-a-i-n. In IPA phonetic transcription, it is represented as /steɪn/. The "s" is pronounced as the voiceless alveolar fricative /s/, the "t" as the voiceless alveolar plosive /t/, the "a" as the open back unrounded vowel /æ/, the "i" as the diphthong /eɪ/, and the "n" as the voiced alveolar nasal /n/. This word refers to a discoloration or mark on a surface.
Stain can be defined as a discoloration or spot caused by a foreign substance that has been absorbed into or adhered to a surface. It refers to a mark that alters the appearance of a material or object, often resulting in a visible flaw or blemish. Stains can occur on various surfaces such as fabrics, wood, metal, or even the human body.
In the context of fabrics or textiles, a stain typically occurs when a liquid or substance comes into contact with the material, leaving a visible mark that is difficult to remove. Common examples include coffee stains, ink stains, or food stains. These marks are considered undesirable as they may permanently alter the color or texture of the fabric.
When it comes to wood or other porous materials, stains are often used deliberately to enhance the appearance or protect the surface. Wood stain, for instance, is a substance applied to wooden surfaces to alter their color or to provide a protective layer. In this case, the stain impregnates the wood, penetrating the pores and creating a lasting change in the appearance.
Stains can also refer to marks or discolorations on human teeth, caused by factors such as poor dental hygiene, certain foods or drinks, or the use of tobacco products. Dental stains can range from surface-level discoloration to deeper, more stubborn stains that require professional treatment.
Overall, stains are commonly seen as undesirable marks, but can also serve a purpose in enhancing or protecting certain materials or surfaces.

The word stain has its origin in Middle English, derived from the Old Norse word steinn or stainn. The Old Norse word meant blood, color, or layer. The term further evolved from the Old English word stægen, which meant a mark, spot, or blemish. Ultimately, the word can be traced back to the Proto-Germanic word staigijan, which meant to paint, color, or stain.
