Round-trip translation (RTT), also known as back-and-forth translation, recursive translation and bi-directional translation, is the process of translating a word, phrase or text into another language (forward translation), then translating the result back into the original language (back translation), using machine translation (MT) software.
 It is often used by laypeople to evaluate a machine translation system, or to test whether a text is suitable for MT when they are unfamiliar with the target language.
 Because the resulting text can often differ substantially from the original, RTT can also be a source of entertainment.
Fill-Ins, also known as Fill-It-Ins or Word Fills, are a variation of the common crossword puzzle in which words, rather than clues, are given.
 Fill-Ins are common in puzzle magazines along with word searches, cryptograms, and other logic puzzles.
 Some consider Fill-Ins to be an easier version of the crossword.
 Since the Fill-In requires no outside knowledge of specific subjects, one can solve the puzzle in another language.
Somrai (Sumrey), also known as Sibine (Shibne), is an Afro-Asiatic language spoken in the southwestern Chadian prefectures of Tandjilé and Lai.
 The speakers or Somrai are not bilingual; the language is not mutually intelligible with any other, as its highest lexical similarity with another language is with Ndam (42%).
 Most of the speakers, who call themselves Shibne or Sibine, generally practice traditional religions, Christianity, or Islam.
Tause, also known as Doa or Darha, is a poorly known Papuan language of Indonesia spoken by some 350 people.
 The Tause only made contact with the outside world in 1982.
 Their language has been widely reported to be related to the neighboring Lakes Plain languages; however, this conclusion is based on little evidence.
 Recently Malcolm Ross placed Tause in his East Bird's Head – Sentani family, along with another language isolate and two small families, but this was motivated more by an attempt to spark further research than an actual claim of relationship.
Mpra, or Mpre, is an extinct language spoken in the village of Butei ( ) in central Ghana, located between the towns of Techiman and Tamale near the confluence of the Black and White Voltas. Mpra has been difficult to classify due to its divergent vocabulary.
 It is known only from a 70-word list given in a 1931 article.
 Blench (2007) considers it to be a possible language isolate.
 A poorly attested language spoken in the nearby village of Tuluwe, Mpur, may also turn out to be yet another language isolate.
 Both Butie and Tuluwe are located near the village of Mpaha.
Frederick IV of Hohenstaufen (1145–1167) was duke of Swabia, succeeding his cousin, Frederick Barbarossa, Holy Roman Emperor, in 1152.
Language transfer (also known as L1 interference, linguistic interference, and crosslinguistic influence) refers to speakers or writers applying knowledge from one language to another language.
 It is the transfer of linguistic features between languages in the speech repertoire of a bilingual or multilingual individual, whether from first to second, second to first or many other relationships.
 It is most commonly discussed in the context of English language learning and teaching, but it can occur in any situation when someone does not have a native-level command of a language, as when translating into a second language.
Hans Krag (born 14 December 1904 in Christiania, died 27 January 1984 in Søgne) was a Norwegian author, publisher and translator, known i.a. for his works on heraldry.
 His works include the book "Norsk heraldisk mønstring fra Frederik IV's regjeringstid 1699–1730", with Norwegian arms from the reign of Frederick IV, and articles in "Heraldisk Tidsskrift".
 He was the first Norwegian member of L'Académie Internationale d'Héraldique.
 He also published works on genealogy.
Frederick IV (1382 – 24 June 1439), also known as Frederick of the Empty Pockets (German: "Friedrich mit der leeren Tasche" ), a member of the House of Habsburg, was Duke of Austria from 1402 until his death.
 As a scion of the Habsburg Leopoldian line, he ruled over Further Austria and the County of Tyrol from 1406 onwards.
Frederick I (German: "Friedrich I" , Italian: "Federico I" ; 1122 – 10 June 1190), also known as Frederick Barbarossa (Italian: "Federico Barbarossa" ), was the Holy Roman Emperor from 1155 until his death.
 He was elected King of Germany at Frankfurt on 4 March 1152 and crowned in Aachen on 9 March 1152.
 He became King of Italy in 1155 and was crowned Roman Emperor by Pope Adrian IV on 18 June 1155.
 Two years later, the term "sacrum " ("holy") first appeared in a document in connection with his Empire.
 He was later formally crowned King of Burgundy, at Arles on 30 June 1178.
 He was named "Barbarossa " by the northern Italian cities which he attempted to rule: Barbarossa means "red beard" in Italian; in German, he was known as "Kaiser Rotbart ", which has the same meaning.
