Parseltongue is the language of serpents (as well as other magical serpent-based creatures, like the Runespoor) and those who can converse with them. An individual who can speak Parseltongue is known as a Parselmouth. It is a very uncommon skill, and is typically hereditary. Nearly all known Parselmouths are descended from Salazar Slytherin with Harry Potter being the notable exception.

A gynoid is anything which resembles or pertains to the female human form. It is also used in American English medical terminology as a shortening of the term Gynecoid (Gynaecoid in British English).Gynoid has not gained popular usage to refer specifically to female robots as the term android is used almost universally to refer to robotic humanoids regardless of apparent gender. Android is perceived as implying a male-styled robot according to some cultural readings however.

A Microcassette (often written generically as microcassette) is an audio storage medium introduced by Olympus in 1969. It uses the same width of magnetic tape as the Compact Cassette but in a much smaller container. By using thinner tape and half or a quarter the tape speed, microcassettes can offer comparable recording time to the compact cassette. The original standard microcassette, the MC60, gives 30 minutes recording per side at its standard speed of 2.4 cm/s, and double that duration at 1.2 cm/s; an MC90, giving 45 minutes per side @ 2.4 cm/s, is also available from a few manufacturers.

Glitter bombing is an emerging act of protest in the United States in which activists throw glitter on people at public events. Glitter bombers have frequently been motivated by their target's anti-gay beliefs. Glitter bombing is "technically assault and battery" according to Mark R. Vernazza, a legal associate at Edwards Angell Palmer & Dodge LLP, although Vernazza also states that without proof of intent to injure, prosecution is unlikely.

Pentaborane, also called pentaborane(9) to distinguish it from B5H11, is an inorganic compound with the formula B5H9. It is one of the most common boron hydride clusters, although it is a highly reactive compound. Because of its high reactivity toward oxygen, it was once evaluated as rocket or jet fuel. Like many of the smaller boron hydrides, pentaborane is colourless, diamagnetic and volatile.

An inductor (or reactor or coil) is a passive two-terminal electrical component used to store energy in a magnetic field. Any conductor has inductance although the conductor is typically wound in loops to reinforce the magnetic field.
Due to the time-varying magnetic field inside the coil, a voltage is induced, according to Faraday's law of electromagnetic induction, which by Lenz's law opposes the change in current that created it. Inductors are one of the basic components used in electronics where current and voltage change with time, due to the ability of inductors to delay and reshape alternating currents. Inductors called chokes are used as parts of filters in power supplies or can be used to block AC signals from passing through a circuit.

The term should be distinguished from "false cognates", which are similar words in different languages that appear to have a common historical linguistic origin (whatever their current meaning) but actually do not.
As well as complete false friends, use of loanwords often results in the use of a word in a restricted context, which may then develop new meanings not found in the original language.

A technical pen is a specialized instrument used by an engineer, architect, or drafter to make lines of constant width for architectural, engineering, or technical drawings. It has been also generally called "rapidograph", although that particular name is officially a trademarked line of products made by German company Rotring, and by American manufacturer Chartpak, Inc. when they purchased the rights from Rotring to produce the pens in the USA under the Koh-I-Noor brand.
Most technical pens use ink cartridges which can be refilled or replaced.

Allotropy or allotropism is the property of some chemical elements to exist in two or more different forms, known as allotropes of these elements. Allotropes are different structural modifications of an element; the atoms of the element are bonded together in a different manner.
Take carbon for example: 4 common allotropes of carbon are diamond (where the carbon atoms are bonded together in a tetrahedral lattice arrangement), graphite (where the carbon atoms are bonded together in sheets of a hexagonal lattice), graphene (single sheets of graphite), and fullerenes (where the carbon atoms are bonded together in spherical, tubular, or ellipsoidal formations).
The term allotropy is used for elements only, not for compounds. The more general term, used for any crystalline material, is polymorphism. Allotropy refers only to different forms of an element within the same phase (i.e. different solid, liquid or gas forms); the changes of state between solid, liquid and gas in themselves are not considered allotropy.
For some elements, allotropes have different molecular formulae which can persist in different phases – for example, two allotropes of oxygen (dioxygen, O2 and ozone, O3), can both exist in the solid, liquid and gaseous states. Conversely, some elements do not maintain distinct allotropes in different phases – for example phosphorus has numerous solid allotropes, which all revert to the same P4 form when melted to the liquid state.

Synchysis is an interlocked word order, in the form A-B-A-B; which often display change and difference. This poetry form was a favorite with Latin poets. They are often employed to demonstrate such change within the event in which they are situated; on occasion, there are synchyses within a poem which were not intended but happened to be written in such a way.
A synchysis may be opposed to chiasmus, which is in the form A-B-B-A.
A line of Latin verse in the form adjective A - adjective B - verb - noun A - noun B, with the verb in the center (or a corresponding chiastic line, again with the verb in the center), is known as a golden line. An example of this is aurea purpuream subnectit fibula vestem, "a golden clasp bound her purple cloak" (Virgil, Aeneid 4.139): the line translates word-by-word as "golden purple bound clasp cloak" (endings on the Latin words indicate their syntactical relationship, where in English word order would do the same job).

A transpositional pun is a complicated pun format with two aspects. It involves transposing the words in a well-known phrase or saying to get a daffynition-like clever redefinition of a well-known word unrelated to the original phrase. The redefinition is thus the first aspect, the transposition the second aspect.
As a result, transpositional puns are considered among the most difficult to create, and commonly the most challenging to comprehend, particularly for non-native speakers of the language in which they're given (most commonly English).

In traditional prescriptive grammar, a solecism is something perceived as a grammatical mistake or absurdity, or even a simply non-standard usage. The word was originally used by the Greeks for what they perceived as mistakes in their language. Ancient Athenians considered the dialect of the inhabitants of their colony Soli in Cilicia to be a corrupted form of their own pure Attic dialect, full of "solecisms" (Greek: σολοικισμοί, soloikismoí; Sing.: σολοικισμός, soloikismós).
Here are some examples of usages often regarded as solecisms in standard English:
- "This is just between you and I" for "This is just between you and me" (hypercorrection to avoid the common "you and me" form in the predicate of copulative sentences, even though "me" is the standard pronoun for the object of a preposition)
- "He ain't going nowhere" for "He isn't [or "he's not"] going anywhere" or "he is going nowhere" (dialectical usage; see "ain't") and double negative
- "Whom shall I say is calling?" for "Who shall I say is calling?" (hypercorrection resulting from the perception that "whom" is a formal version of "who" or that the pronoun is functioning as an object when, in fact, it is a subject [One would say, "Shall I say he is calling?])
- Irregardless for regardless (nonstandard usage from analogy with constructions like "irreverent," "irrespective," and "irrevocable," where the negative prefix "in-" changes to "ir-" but becomes redundant because of "-less")
- "The woman, she is here" for "The woman is here" or "She is here" (nonstandard usage with the double subject "she")
- "She can't hardly sleep" for "She can hardly sleep" (a double negative, as both "can't" and "hardly" have a negative meaning)
- "The issue is, is his attitude" for "The issue is his attitude" (see double copula)
- "Substituting A for B" when the intended meaning is "substituting B for A" or "replacing A with B", i.e. "removing A and putting B in its place."
- "The reason being..." for "The reason is..."

Paregoric is sometimes confused with Laudanum, because their chemical names are similar: Camphorated Tincture of Opium (Paregoric) vs. Tincture of Opium (Laudanum). However, Laudanum contains 10 milligrams of morphine per milliliter, 25 times more than Paregoric. Confusion between the two drugs has led to overdose and deaths in several patients. Thus the term "Paregoric" should be used instead of "Camphorated Opium Tincture," since the latter may be confused with Laudanum.

A luthier is someone who makes or repairs lutes and other string instruments. In the United States, the term is used interchangeably with a term for the specialty of each maker, such as violinmaker, guitar maker, lute maker, etc. The word luthier comes from the French word luth, which means "lute".
The craft of making string instruments, or lutherie, is commonly divided into two main categories: makers of stringed instruments that are plucked or strummed and makers of stringed instruments that are bowed. Since bowed instruments require a bow, the second category includes a subtype known as a bow maker or archetier.

Prognathism (also known as Habsburg Jaw) is a term used to describe the positional relationship of the mandible and/or maxilla to the skeletal base where either of the jaws protrudes beyond a predetermined imaginary line in the coronal plane of the skull. In general dentistry, oral and maxillofacial surgery and orthodontics this is assessed clinically or radiographically (cephalometrics). The word prognathism derives from Greek pro (forward) and gnathos (jaw). One or more types of prognathism may result in the common condition of malocclusion (including overbite), where an individual's top teeth do not align with the lower teeth.
