Context: Punctuation is "the use of spacing, conventional signs, and certain typographical devices as aids to the understanding and the correct reading, both silently and aloud, of handwritten and printed texts." Another description is: "The practice, action, or system of inserting points or other small marks into texts, in order to aid interpretation; division of text into sentences, clauses, etc., by means of such marks.", In grammar, a clause is the smallest grammatical unit that can express a complete proposition. A typical clause consists of a subject and a predicate, the latter typically a verb phrase, a verb with any objects and other modifiers. However, the subject is sometimes not expressed, often the case in null-subject languages if the subject is retrievable from context, but it sometimes also occurs in other languages such as English (as in imperative sentences and non-finite clauses)., In written language, a logogram or logograph is a written character that represents a word or phrase. Chinese characters and Japanese kanji are logograms; some Egyptian hieroglyphs and some graphemes in cuneiform script are also logograms. The use of logograms in writing is called "logography". A writing system that is based on logograms is called a "logographic system"., A planned or constructed language (sometimes called a conlang) is a language whose phonology, grammar, and vocabulary have been consciously devised for human or human-like communication, instead of having developed naturally. It is also referred to as an artificial or invented language. There are many possible reasons to create a constructed language, such as: to ease human communication (see international auxiliary language and code), to give fiction or an associated constructed setting an added layer of realism, for experimentation in the fields of linguistics, cognitive science, and machine learning, for artistic creation, and for language games., Esperanto (or ; in Esperanto: ) is a constructed international auxiliary language. It is the most widely spoken constructed language in the world. The Polish-Jewish ophthalmologist L. L. Zamenhof published the first book detailing Esperanto, "," on 26 July 1887. The name of Esperanto derives from " ("" translates as "one who hopes"), the pseudonym under which Zamenhof published Unua Libro., Esperanto is written in a Latin alphabet of twenty - eight letters , with upper and lower case . This is supplemented by punctuation marks and by various logograms , such as the numerals 0 -- 9 , currency signs such as $ , and mathematical symbols . Twenty - two of the letters are identical in form to letters of the English alphabet ( q , w , x , and y being omitted ) . The remaining six have diacritic marks ,  ,  ,  ,  ,  , and  ( that is , c , g , h , j , and s circumflex , and u breve ) . The full alphabet is : In handwritten Esperanto , the diacritics pose no problem . However , since they do n't appear on standard alphanumeric keyboards , various alternate methods have been devised for representing them in printed and typed text . The original method was a set of digraphs now known as the `` h - system '' , but with the rise of computer word processing a so - called `` x-system '' has become equally popular . These systems are described below . However , with the advent of Unicode , the need for such work - arounds has lessened . Unique to the Esperanto script is the spesmilo ( 1000 specie ) sign , an Sm monogram for a now - obsolete international unit of auxiliary Esperanto currency used by a few British and Swiss banks before World War I. It has been assigned the Unicode value U +20B7 , though in ordinary fonts it is often transcribed as Sm , usually italic ., Ludwik Lejzer Zamenhof (), usually credited as L. L. Zamenhof, was a Polish-Jewish medical doctor, inventor, and writer. He is most widely known for creating Esperanto, the most successful constructed language in the world. He grew up fascinated by the idea of a world without war and believed that this could happen with the help of a new international auxiliary language, which he first developed in 1873 while still in school., Dr. Esperanto's International Language, usually referred to as Unua Libro, was the first publication to describe Esperanto, then called the International Language. It was first published in Russian on July 26, 1887 in Warsaw, by Polish oculist L. L. Zamenhof. Over the next few years editions were published in Polish, Russian, Hebrew, French, German, and English. This booklet included the Lord's Prayer, some Bible verses, a letter, poetry, the sixteen rules of grammar and 900 roots of vocabulary. In the book Zamenhof declared, "an international language, like a national one, is common property" and renounced all rights to the language, effectively putting it into the public domain. Zamenhof signed the work as "Doktoro Esperanto" (Doctor One-Who-Hopes). Those who learned the new language began to call it "Esperanto" after Zamenhof's pen name, and Esperanto soon became the official name of the language., An international auxiliary language (sometimes abbreviated as IAL or auxlang) or interlanguage is a language meant for communication between people from different nations who do not share a common first language. An auxiliary language is primarily a second language., Subject: esperanto orthography, Relation: instance_of, Options: (A) action (B) bible (C) case (D) clause (E) code (F) constructed language (G) description (H) division (I) grammar (J) idea (K) international auxiliary language (L) july (M) language (N) letter (O) machine (P) pen name (Q) people (R) poetry (S) practice (T) predicate (U) property (V) punctuation (W) school (X) share (Y) text (Z) understanding ([) verb (\) war (]) work (^) writing
