Dirt is unclean matter, especially when in contact with a person's clothes, skin or possessions when they are said to become dirty. Common types of dirt include:
- dust — a general powder of organic or mineral matter
- filth — foul matter such as excrement
- grime — a black, ingrained dust such as soot
- soil — the mix of clay, sand and humus which lies over the bedrock

Cleaning [link]
When things are dirty they are usually cleaned with solutions like hard surface cleaner and other chemicals; much domestic activity is for this purpose — washing, sweeping and so forth.[1]
In a commercial setting, a dirty appearance will give a bad impression of a place such as a restaurant. The dirt in such cases may be classified as temporary, permanent and deliberate. Temporary dirt is streaks and detritus that may be removed by ordinary daily cleaning. Permanent dirt is ingrained stains or physical damage which require major renovation to remove. Deliberate dirt is that which results from design decisions such as decor in dirty yellow or grunge styling.[2]
Disposal [link]
As cities developed, arrangements were made for the disposal of dirt. In Britain, the Public Health Act 1875 required households to place their refuse into a container which could be moved so that it could be carted away. This was the first legal creation of the dustbin.[3]
Foci [link]
Computer keyboards are especially dirty as, on average, they contain 70 times more microbes than a lavatory seat.[4]
Health [link]
Modern society is now thought to be excessively clean. Lack of contact with microorganisms in dirt when growing up is hypothesised to be the cause of the epidemic of allergies such as asthma.[5] The human immune system requires activation and exercise in order to function properly and exposure to dirt may achieve this.[6] For example, the presence of staphylococcus bacteria on the surface of the skin regulates the inflammation which results from injury.[7]
People and animals may eat dirt. This is thought to be caused by mineral deficiency and so the condition is commonly seen in pregnant women.
Neurosis [link]
People may become obsessed by dirt and engage in fantasies and compulsive behaviour about it, such as making and eating mud pies.[8] The source of such thinking may be genetic, as the emotion of disgust is common and a location for it in the brain has been proposed.[9]
Exhibitions and studies [link]
A season of artworks and exhibits on the theme of dirt was sponsored by the Wellcome Trust in 2011. The centrepiece was an exhibition at the Wellcome Collection showing pictures and histories of notable dirt such as the great dust heaps at Euston and King's Cross in the 19th century and the Fresh Kills landfill which was once the world's largest.[10]

Dirt (Florida Georgia Line song)
"Dirt" is a song recorded by American country music duo Florida Georgia Line. It is the first single from their sophomore studio album Anything Goes, which was released on October 14, 2014.
Content
Written by Rodney Clawson and Chris Tompkins, the song is a mid-tempo ballad about various life events centering on dirt.
The final lines of the song include the lyrics "You know you came from it / Someday you'll return to it", which the duo initially did not want to include as they felt it was a cliché. However they eventually decided to include the line. Brian Kelley, one-half of the duo, told the Chicago Sun-Times, "I think a 'Cruise'-type song would have been accepted, but just when you think you have FGL figured out, we wanted to go against the grain and change it up with a song like 'Dirt'".
Music video
The music video was directed by Nigel Dick. It follows the life of a married couple, alternating between the past and present, where the family is gathered for the mother's funeral. It stars J. D. Souther in the leading role and Lindsay Heyser as the young Rosie.
Seal (emblem)
A seal is a device for making an impression in wax, clay, paper, or some other medium, including an embossment on paper, and is also the impression thus made. The original purpose was to authenticate a document, a wrapper for one such as a modern envelope, or the cover of a container or package holding valuables or other objects.
The seal-making device is also referred to as the seal matrix or die; the imprint it creates as the seal impression (or, more rarely, the sealing). If the impression is made purely as a relief resulting from the greater pressure on the paper where the high parts of the matrix touch, the seal is known as a dry seal; in other cases ink or another liquid or liquefied medium is used, in another color than the paper.
In most traditional forms of dry seal the design on the seal matrix is in intaglio (cut below the flat surface) and therefore the design on the impressions made is in relief (raised above the surface). The design on the impression will reverse (be a mirror-image of) that of the matrix, which is especially important when script is included in the design, as it very often is. This will not be the case if paper is embossed from behind, where the matrix and impression read the same way, and both matrix and impression are in relief. However engraved gems were often carved in relief, called cameo in this context, giving a "counter-relief" or intaglio impression when used as seals. The process is essentially that of a mould.

Seal (contract law)
In the law, a seal affixed to a contract or other legal instrument has had special legal significance at various times in the jurisdictions that recognise it. In the courts of common law jurisdictions, a contract which was sealed ("made under seal") was treated differently from other written contracts (which were "made under hand"), although this practice gradually fell out of favour in most of these jurisdictions in the 19th and early 20th century. The legal term seal arises from the wax seal used throughout history for authentication (among other purposes).
Originally, only a wax seal was accepted as a seal by the courts, but by the 19th century many jurisdictions had relaxed the definition to include an impression in the paper on which the instrument was printed, an embossed paper wafer affixed to an instrument, a scroll made with a pen, or the printed words "Seal" or "L.S." (standing for the Latin term locus sigilli meaning "place of the seal").
Notwithstanding their reduced significance, seals are still used on contracts, usually in the impression on paper form.
