Context paragraphs:
Nomenclator (nomenclature): A nomenclator ( ; English plural nomenclators, Latin plural nomenclatores; derived from the Latin "nomen"- name + "calare" - to call), in classical times, referred to a slave whose duty was to recall the names of persons his master met during a political campaign.  Later this became names of people in any social context and included other socially important information.

Epsilon Piscium: Epsilon Piscium (Epsilon Psc, ε Piscium, ε Psc) is the Bayer designation for a star approximately 182 ly away from the Earth, in the constellation Pisces.  It is a yellow-orange star of the G9 III or K0 III spectral type, meaning it has a surface temperature around 5,000 kelvins.  This is a normal giant star, slightly cooler in surface temperature, yet brighter and larger than the Sun.  It is a suspected occultation double, with both stars having the same magnitude, separated by 0.25 arcsecond.

Pisces (constellation): Pisces is a constellation of the zodiac.  Its name is the Latin plural for fish.  It lies between Aquarius to the west and Aries to the east.  The ecliptic and the celestial equator intersect within this constellation and in Virgo.  Its symbol is (Unicode ♓).

Forceps: Forceps (plural forceps or considered a plural noun without a singular, often a pair of forceps; the Latin plural "forcipes" is no longer recorded in most dictionaries) are a handheld, hinged instrument used for grasping and holding objects.  Forceps are used when fingers are too large to grasp small objects or when many objects need to be held at one time while the hands are used to perform a task.  The term 'forceps' is used almost exclusively within the medical field.  Outside medicine, people usually refer to forceps as tweezers, tongs, pliers, clips or clamps.

Fasti: In ancient Rome, the fasti (Latin plural) were chronological or calendar-based lists, or other diachronic records or plans of official and religiously sanctioned events.  After Rome's decline, the word "fasti" continued to be used for similar records in Christian Europe and later Western culture.

Plural form of words ending in -us: In English, the plural form of words ending in "-us", especially those derived from Latin, often replaces "-us" with "-i".  There are many exceptions, some because the word does not derive from Latin, and others due to custom ("e.g.", "campus", plural "campuses").  Conversely, some non-Latin words ending in "-us" and Latin words that did not have their Latin plurals with "-i" form their English plurals with "-i".  Some words' plurals end in "-i" even though they are not Latin, or that is not the Latin plural, "e.g.", "octopi" as a plural for octopus.  Prescriptivists consider these forms incorrect, but descriptivists may simply describe them as a natural evolution of language.

Munera (ancient Rome): In ancient Rome, munera (Latin plural) were public works provided for the benefit of the Roman people ("populus Romanus") by individuals of high status and wealth.  The word "munera", singular "munus" (cf. English "munificence") means "duty, obligation", expressing the individual's responsibility to provide a service or contribution to his community.  "Munera" are owing to the private largesse of an individual, in contrast to the "ludi", "games," athletic contests or spectacles sponsored by the state.

Beta Piscium: Beta Piscium (β Piscium), also known by its traditional name Fum al Samakah, is a blue-white hued star in the zodiac constellation of Pisces.  Its apparent magnitude is 4.40, meaning it can be faintly seen with the naked eye.  Based on parallax estimates made by the Hipparcos spacecraft, the system is located about 410 light-years (125 parsecs) away.

Corrector: A corrector (English plural "correctors", Latin plural "correctores") is a person or object practicing correction, usually by removing or rectifying errors.

Radius: In classical geometry, a radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also the length of any of them.  The name comes from the Latin "radius", meaning ray but also the spoke of a chariot wheel.  The plural of radius can be either "radii" (from the Latin plural) or the conventional English plural "radiuses".  The typical abbreviation and mathematical variable name for radius is r. By extension, the diameter d is defined as twice the radius:
