quilo-

== Catalan == === Etymology 1 === Borrowed from French kilo-, from Ancient Greek χίλιοι (khílioi, “thousand”). ==== Alternative forms ==== kilo- ==== Prefix ==== quilo- kilo- (SI prefix expressing 103 of the base unit) ===== Usage notes ===== The letter k is not normally used in Catalan. Instead, Catalan orthography calls for using the qu digraph to represent the /k/ sound before an e or an i. Therefor, when the metric system was introduced into Catalan, the prefix kilo- was originally spelled quilo-. With the advent of k as a standard international abbreviation, usage of kilo- has become not only acceptable, but also more common than the traditional spelling. However, traditionalists still insist upon the use of quilo-. ===== Derived terms ===== === Etymology 2 === From Ancient Greek χεῖλος (kheîlos, “lip, edge”). ==== Prefix ==== quilo- (before a vowel quil-) cheilo- (combining form used in scientific neologisms to indicate the lips or an edge) ===== Derived terms ===== quiloplàstia (“cheiloplasty”) === Etymology 3 === From Ancient Greek χυλός (khulós, “secretion, bile”). ==== Prefix ==== quilo- (before a vowel quil-) chole- (combining form used in scientific neologisms to indicate bile) ===== Derived terms ===== quilopericardi (“presence of bile in the pericardial fluid”) ===== Related terms ===== col- (“relating to bile”) quil (“bile”) === Further reading === “quilo-”, in Diccionari de la llengua catalana [Dictionary of the Catalan Language] (in Catalan), second edition, Institute of Catalan Studies [Catalan: Institut d'Estudis Catalans], April 2007 == Galician == === Prefix === quilo- kilo- ==== Derived terms ==== From . === Further reading === “quilo-”, in Dicionario da Real Academia Galega (in Galician), A Coruña: Royal Galician Academy, 2012–2026 == Portuguese == === Alternative forms === kilo- === Prefix === quilo- kilo- (103) ==== Derived terms ==== === Further reading === “quilo-”, in Dicionário Aulete Digital (in Portuguese), Rio de Janeiro: Lexikon Editora Digital, 2008–2026 “quilo-”, in Dicionário Priberam da Língua Portuguesa (in Portuguese), Lisbon: Priberam, 2008–2026 == Spanish == === Prefix === quilo- alternative spelling of kilo- ==== Derived terms ==== === Further reading === “quilo-”, in Diccionario de la lengua española [Dictionary of the Spanish Language] (in Spanish), online version 23.8.1, Royal Spanish Academy [Spanish: Real Academia Española], 15 December 2025
