Οι περισσότεροι χημικοί όροι που έχουν συγκεντρωθεί προέρχονται από ξένες λέξεις, κυρίως λατινικές, πολλές από τις οποίες έχουν ελληνική προέλευση ή ανάλογη λέξη από κοινή ρίζα. Δεν επιχειρείται η ερμηνεία ή η περιγραφή του όρου, με κάποιες εξαιρέσεις. Επίσης κατ’ εξαίρεση, σε μερικές περιπτώσεις αναπτύσσεται το ιστορικό πλαίσιο στο οποίο βασίστηκε η δημιουργία της λέξης. Οι λέξεις που ετυμολογούνται ανήκουν και σε ευρύτερα πεδία, όπως την ορυκτολογία, τη βιοχημεία, τη φαρμακολογία και μερικά εμπορικά προϊόντα.

Most of the chemical terms that have been collected come from foreign words, mainly Latin, many of which have Greek origin or similar word of common origin. It does not attempt to interpret or describe the term, with some exceptions. Also by way of exception, in some cases the historical context on which the creation of the word was based is developed. The words that are said to belong to broader fields, such as mineralogy, biochemistry, pharmacology and some commercial products.

Star Trek Spectral Classification

"Stars can generally be classified by their color. A purple star is always Class O, a yellow star is always Class G. However, there can be vast differences within each class. Most Class M stars are tiny and don't emit much light... however, many K- and G-type stars can evolve into red giants. That makes them Class M, but they are NOTHING like the tiny stars that make up the vast majority of Class M stars. Since most stars spend most of their lives on the Main Sequence, the descriptions on this page can be applied to the majority of stars.

Star Trek Nebula Classification

"A nebula is an interstellar cloud of dust, gas, and plasma, where star formation usually occurs. In the year 2400, the Federation introduced a new system to classify nebulae. The new system first assigns the nebula a letter designation based upon its general composition. If the nebula has any unusual quirks, it is assigned an additional number designation. For example, a Class F2 Nebula is a Dark Nebula that contains disruptive electromagnetic radiation."

Star Trek Planetary Classification

"A planet is a celestial body in orbit around a star or stellar remnants, that has sufficient mass for self-gravity and is nearly spherical in shape. A planet must not share its orbital region with other bodies of significant size (except for its own satellites), and must be below the threshold for thermonuclear fusion of
deuterium. If a celestial body meets those requirements, it is considered a planet; at that point, the planet is further classified by its atmosphere and surface conditions into one of twenty-two categories."

Klassifikation für Musikbibliotheken

"Die Klassifikation ermöglich das Verzeichnen von Musikalien (grafische Musikaufzeichnungen, Musikdrucke, Noten, akustische Musikaufzeichnungen, Musiktonträger, Dateien). Facetten der Klassifikation können unter anderem folgende sein: bei der Aufnahme genutzte Stimmen und Musikinstrumente in standardisierter Abkürzung, Gattung, Genre, Form, Stilrichtung, geografischer Bezug, Anlass, Zweck, sozialer Träger, außermusikalischer inhaltlicher Bezug, zeitlicher Bezug Erscheinungsform, Spieldauer, Musikfarbe, Popularität, technisches Format)."

"The classification makes it possible to record music (graphical music recordings, music prints, notes, acoustic music recordings, musical instruments, files). Facets of the classification may include the following: voices and musical instruments used in the recording in standardized abbreviation, genre, genre, form, stylistic direction, geographic reference, occasion, purpose, social carrier, Popularity, technical format)."
