An auto-antonym (sometimes spelled autantonym), or contranym (originally spelled contronym), is a word with a homograph (a word of the same spelling) that is also an antonym (a word with the opposite meaning). Variant names include antagonym, Janus word (after the Roman god), enantiodrome, and self-antonym. It is a word with multiple meanings, one of which is defined as the reverse of one of its other meanings.
For example, the word "fast" can mean "moving quickly" as in "running fast," or it can mean "not moving" as in "stuck fast." To buckle can mean "to fasten" when used transitively or "to bend then break" intransitively. "To weather" can mean "to endure" (intransitive) or "to erode" (transitive). However such terms are just how one relates to the meaning of an object enduring or having endured weather, whether it is standing up against said weather unchanged, or being influenced negative by said weather, it is still either way being weathered and the additional valuation of its resultant meaning makes it an auto-anyonym only subjectively; when in actuality the word means simply how an object relates to the influence of weather for better or worse. That is an example of our perception adding meaning to the word where it may not initially imply such a meaning generally that would make it an auto-antonym. "Weedy" can mean "overgrown" ("The garden is weedy") or stunted ("The boy looks weedy"). "To overlook" can mean "to inspect" or "to fail to notice". "Strike", in baseball terms, can mean "to hit the ball" or "to miss the ball". This phenomenon is also called "enantionymy" or "antilogy."

In the process of setting electoral districts, Gerrymandering is a practice that attempts to establish a political advantage for a particular party or group by manipulating geographic boundaries to create partisan, incumbent-protected districts. The resulting district is known as a gerrymander; however, that word can also refer to the process.
Gerrymandering may be used to achieve desired electoral results for a particular party, or may be used to help or hinder a particular group of constituents, such as a political, racial, linguistic, religious or class group.

Scabies, known colloquially as the seven-year itch, is a contagious skin infection that occurs among humans and other animals. It is caused by a tiny and usually not directly visible parasite, the mite Sarcoptes scabiei, which burrows under the host's skin, causing intense allergic itching. The infection in animals (caused by different but related mite species) is called sarcoptic mange.

The phrase carries the connotation that the reader should pay attention to the corresponding differences between the current statement and a previous one, although they are analogous. This term is used frequently in economics, philosophy and in law, to parameterize a statement with a new term, or note the application of an implied, mutually understood set of changes. The phrase is also used in the study of counter-factuals, wherein the requisite change in the factual basis of the past is made and the resulting causalities are followed.

Lunokhod was a series of Soviet robotic lunar rovers designed to land on the Moon between 1969 and 1977. The 1969 Lunokhod 1A was destroyed during launch, the 1970 Lunokhod 1 and the 1973 Lunokhod 2 landed on the moon and the 1977 Lunokhod was never launched. The successful missions were in operation concurrently with the Zond and Luna series of Moon flyby, orbiter and landing missions. The Lunokhods were primarily designed to support the Soviet manned moon missions and to be used as automatic remote-controlled robots to explore the surface and return pictures. The Lunokhods were transported to the lunar surface by Luna spacecraft, which were launched by Proton rockets. The moon lander part of the Luna spacecraft for Lunokhods were similar to the ones for sample return missions. The Lunokhods were designed by Alexander Kemurdjian at NPO Lavochkin. Not until the 1997 Mars Pathfinder was another remote-controlled vehicle put on an extraterrestrial body. In 2010, nearly forty years after the 1971 loss of signal from Lunokhod 1, the NASA Lunar Reconnaissance Orbiter photographed its tracks and final location, and researchers, using a telescopic pulsed-laser rangefinder, detected the robot's retroreflector.

In manual papermaking, a deckle is a removable wooden frame or "fence" placed into a mould to keep the paper slurry within bounds and to control the size of the sheet produced. After the mold is dipped into a vat of paper slurry, excess water is drained off and the deckle is removed and the mold shaken or "couched" to set the fibers of the paper. Some of the paper slurry passes under the deckle and forms an irregular, thin edge. Paper with a feathered or soft edge is described as having a "deckled" edge, in contrast with a cut edge.
Machine-made paper may artificially have its edges produced to resemble a deckle edge. This is most commonly used for private presses or fancy stationery.
In film processing, deckles are die inserts that set the coating width of a slot die coater or the extrusion width of an extrusion die. They work by constraining the flow as the material exits the die. Since some materials have a tendency to neck in or spread out after leaving the die, deckle position may need to be compensated to achieve the target width.

Font hinting (also known as instructing) is the use of mathematical instructions to adjust the display of an outline font so that it lines up with a rasterized grid. At low screen resolutions, hinting is critical for producing a clear, legible text. It can be accompanied by antialiasing and (on liquid crystal displays) subpixel rendering for further clarity.

Figging is the practice of inserting a piece of ginger root into the anus, vagina or male urethra. Originally applied to horses as a form of deception as to the horse's condition, it now most commonly refers to a practice in BDSM.
Historically, this practice, also known as feaguing, or gingering was used to ginger up older horses in order to deceive the purchaser as to the age and condition of the horse, by having the animal hold its tail and head high and moving around nervously, characteristic of a younger horse.
The ginger, skinned and often carved into the shape of a butt plug, causes an intense burning sensation and discomfort to the subject. If the submissive tightens the muscles of the anus, the sensation becomes more intense. For this reason it is rumored to have been done to recalcitrant wives in the Victorian age to prevent them from clenching during a spanking.
