Perfection is, broadly, a state of completeness and flawlessness.

The term "perfection" is actually used to designate a range of diverse, if often kindred, concepts. These concepts have historically been addressed in a number of discrete disciplines, notably mathematics, physics, chemistry, ethics, aesthetics, ontology, and theology.

The form of the word long fluctuated in various languages. The English language had the alternates, "perfection" and the Biblical "perfectness."

The word "perfection" derives from the Latin "perfectio", and "perfect" — from "perfectus." These expressions in turn come from "perficio" — "to finish", "to bring to an end." "Perfectio(n)" thus literally means "a finishing", and "perfect(us)" — "finished", much as in grammatical parlance ("perfect").

Many modern languages have adopted their terms for the concept of "perfection" from the Latin: the French "parfait" and "perfection"; the Italian "perfetto" and "perfezione"; the Spanish "perfecto" and "perfección"; the English "perfect" and "perfection"; the Russian "совершенный" (sovyershenniy) and "совершенcтво" (sovyershenstvo); the Croatian and Serbian "savršen" and "savršenstvo"; the Czech "dokonalost"; the Slovak "dokonaly" and "dokonalost"; the Polish "doskonały" and "doskonałość."

Nanna Øland Fabricius (born 2 May 1985), better known by her stage name Oh Land, is a Danish singer-songwriter and record producer. She lives in Brooklyn, New York City.

Oh Land was born in Copenhagen, the daughter of Bendt Fabricius, an organist, and Bodil Øland, an opera singer. She is the great-great-grandchild of missionary and ethnographer Otto Fabricius, who published Fauna Groenlandica in 1780, the first zoological observations of Greenland. She is a former student of the Royal Danish and Royal Swedish Ballet schools. However, an injury caused by a slipped disc and spinal fracture put an end to her dancing career, which eventually led her to start making music. Oh Land has a small dog named Ujan that travels with her sometimes. She has been living in the Brooklyn neighbourhood of Williamsburg since January 2010.

Oh Land's debut album, Fauna, was released in her native Denmark on 10 November 2008 by Danish independent label Fake Diamond Records. For her eponymous follow-up album, she worked with producers Dan Carey, Dave McCracken and Lester Mendez. The album was released on 14 March 2011 and peaked at number five on the Danish Albums Chart. It also served as her debut in the United States, where it was released on 15 March 2011 by Epic Records, reaching number 184 on the Billboard 200 chart. An EP with the same name was previously released on 19 October 2010, containing four tracks from the full-length album. On 7 April 2011, she was given the Brink of Fame: Music Artist award at the 2011 NewNowNext Awards.
