English noundossier summary

fiend

An inherited English noun whose earliest recorded sense was enemy or foe, not demon. Old English fēond belonged to a Germanic lexicalized one-who-hates formation; Middle English fẹ̄nd preserved enemy, Satan, demon, possession, and monster senses across extensive spelling variation; modern fiend continues the same English line. OED’s revised 2026 entry marks the literal enemy sense obsolete after the medieval record, explains the Devil as the ultimate Enemy, and documents long-versus-short vowel competition before the long vowel became dominant by the eighteenth century. The Middle English Dictionary independently exposes 188 quotations across eight senses without claiming a complete corpus.

Old Norse verbdossier summary

fjá

Old Norse fjá was a verb meaning to hate. The Dictionary of Old Norse Prose classifies it as poetic and exposes zero prose citations; its glossarium links point to the early form fía and the reconstructed Proto-Germanic *fi(j)ēn-. Cleasby and Vigfússon call the verb obsolete, compare Gothic fijan and Old English feon or fjan, and locate it in Hýmiskviða 22 and Lokasenna 35, with the reflexive fjásk in Skírnismál 33. Fritzner independently gives the same three locations. The normalized verse texts preserve three different grammatical surfaces: goð fjá in Hýmiskviða, mangi fíár in Lokasenna, and Freyr fiásk in Skírnismál. Lexicon Poeticum likewise reports three poetic records, but explicitly warns that its concordance is unreviewed and that dates should be checked. These are source-reported lexical and edited-text records, not directly inspected manuscript objects, and three records in the reviewed poetic concordance are not a census of every Old Norse utterance. The finite verb became a tiny poetic fossil while its inherited participial relative fjándi became the ordinary enemy noun and accumulated 222 citations in ONP's prose corpus. Those corpus totals are not directly frequency-comparable, but the contrast makes the grammatical survival visible. The generated possible runic inscription shown by modern dictionary transcriptions is not historical evidence and is excluded. No historical sound recording exists, so the dossier does not fabricate one exact pronunciation.

Old Dutch masculine noundossier summary

fīunt

Old Dutch fīunt is the normalized headword behind a twenty-six-occurrence historical-dictionary record for enemy or opponent. ONW classifies the noun as synchronically unsegmented but says it was originally the present participle of the verb corresponding to Old High German fīēn and Gothic fijan, a verb no longer known in Dutch. Its frequency table preserves six case-number cells: nominative and genitive singular plus nominative, genitive, dative, and accusative plural. Those are not a complete paradigm. The article displays twenty representative location blocks after warning that locations in the semantic profile have been reduced. Most early Wachtendonck Psalms material is linguistically dated 901–1000 but survives in copies dated 1595–1605, circa 1598, or 1701–1800; no tenth-century manuscript object was inspected. One dfiunt or fiunt gloss aligned with Latin diabolus is textually disputed, and one Groningen psalm gloss is explicitly assigned to Old Frisian by the dictionary. This dossier therefore treats fīunt as a nominal fossil with a partially preserved inflectional record, not as a productive Old Dutch participle or a complete transparent paradigm.

Gothic class-II weak-verb lemmadossier summary

hatizōn

A Gothic weak verb meaning be angry with or at someone, represented by exactly one verified corpus token: present active second-person plural hatizoþ in John 7:23. Project Wulfila and Streitberg align the form with Greek χολᾶτε in the question “are you angry at me?” and analyze the verb with a dative object. The University of Texas derivational grammar builds class-II hatizōn on the consonantal stem hatiz- of hatis “hatred” or “wrath”; Wright independently lists it as a class-II weak verb. The macronized infinitive is a scholarly citation form, while the manuscript writes only the inflected token without a vowel-length mark. The route continues through the reviewed Germanic noun family and a qualified Indo-European comparison, then stops. One corpus token cannot establish spoken rarity, first use, a complete semantic range, exact pronunciation, or one prehistoric essence.

hostel

A lodging place, especially an inexpensive dormitory-style accommodation, continuing the older hospitality branch shared with hospital and hotel.

hotel

A public lodging establishment, borrowed from French hôtel through Old French hostel and ultimately the Latin hospitality family.

intelligence

Capacity for understanding, information, or the organizations that gather it; inherited through French from Latin intelligentia.
