1550-1560: From the Middle English seccioun (in astronomy, “the intersection of two straight lines; a
division of a scale”), from the Old French section, from the Latin sectionem (stem of sectiō) (a cutting; cutting off, excision, amputation of diseased
parts of the body etc), from sectus,
past participle of secāre (to cut),
from the primitive Indo-European root sek
(to cut). The construct was sec(t)
(āre) + -iōn. The meaning “a part
cut off or separated from the rest” dates from the early fifteenth century
while that of a “drawing representing something as if cut through” was from the
1660s. In English, from the 1550s, there
was the sense of “an act of cutting or dividing”; that is now archaic or preserved
only in some aspects of engineering and in medical phrases, most famously the Caesarian
section. The meaning “a subdivision of a
written work, statute etc” was first noted in the 1570s when the structure in
publishing was (more or less) standardized: books divided into chapters, chapters
into sections and sections into paragraphs or breaks, a system still reflected
by modern word-processing software. Section
can have defined meanings (such as in publishing or land law) but the in
general use the synonyms include cut, division, snippet, part, segment, slice,
piece & specimen. Section is a noun
& verb, sectionalism & sectionality are nouns, sectioning is a noun & verb,
sectional & sectionary are nouns & adjectives, sectioned is a verb (and
a non-standard adjective), sectionable is an adjective and sectionally is an
adverb; the noun plural is sections.
Three-piece sectional art, distinguished a triptych in that the three sections are hung separately. Some commercial galleries do describe such products as "triptychs" because the word has such an association with "high art".
In music, although functionally the distinctions had long
been understood, the idea of sections in a band or orchestra didn’t come into
use until the 1880s (the sections either by type (strings) or function (rhythm). The use of section to describe the one square
mile (640 acres) blocks used for purposes of sub-dividing public lands dates
from 1785. The famous “section 8” began
as World War II (1939-1945) US military slang referring to the passage in army
regulations under which as soldier could be discharged from the service for
reasons of mental illness (not necessarily defined as insanity). The verb section came into use in publishing
in the early nineteenth century in the sense of “divide a text into sections”,
extended by the 1890s to “cut through so as to present a section”. The adjective sectional in the sense of “pertaining
to a division of a larger part” was first noted in 1806 but it is mere
coincidence this was the year in which the thousand year old Holy Roman Empire
was dissolved. It originally did mean “of
or pertaining to some particular section or region of a country as distinct
from others”, something would soon often be heard in the US political
vocabulary in the decades leading up to the Civil War (1861-1965). The noun sectionalism emerged in parallel an
originally meant “sectional prejudice or spirit; the clashing of sectional
interests” but it soon added the sense “a confinement of interests to a local
sphere”. It was in use in US English by
1836 but, again under the influence of those forces which would lead to the
Civil War, it was in frequent use by the mid-1850s.
The meaning “composed or made up of several independent
sections that fit together” was in use in engineering and other mechanical fields
by the mid-eighteenth century. The
specific noun meaning “piece of furniture composed of sections which can be
used separately” appeared in the early 1960s (a clipping of sectional seat,
sectional sofa etc in use since 1949) but the preferred modern descriptor is “modular”. The noun cross-section (section of something
made by a plane passing through it at a right angle to one of its axes) dates
from 1748 and was first applied to the sketches and plans of engineers and
architects. In the early twentieth
century, it picked up the figurative sense of “a representative sample”, emerging
apparently in the social sciences before entering general use. The noun subsection (also as sub-section) (part
or division of a section) dates from the 1620s.
The noun midsection (also as mid-section) (middle of the human body, the
midriff or belly) was coined in the 1930s for commercial purposes. Other forms (quarter-section, half-section,
multi-section, un-sectioned, bisection etc were coined as the need arose.
Lindsay Lohan in sections, hung above a "sectional sofa". "Sectional furniture" was first advertised in the late 1940s and offered more flexibility in that the pieces could be assembled in a variety of configurations, better to suit the available space. The modern trend is to describe such pieces as "modular furniture" but the art is still sectional; modular art is something different.
The military slang (as “to section” or “section 8”)
referred to World War II (1939-1945) US Army regulations (detailed in Section
VIII) under which an individual could be dismissed from the service on mental
health grounds. These grounds provided
for the discharge of men who were deemed mentally unfit for military service so
didn’t exactly follow the conventions followed in civilian medicine; proven (or
confessed) homosexuality could for example be the grounds for a Section VIII discharge. The term entered popular culture in the
post-war years when it was used in fictional depictions of military life, often
as a humorous device following the attempts of soldiers to be “sectioned” as a
way out of the military. Most militaries
have since adopted practices which align more closely with the mainstream handling
of mental health conditions.
The Caesarian section (delivery of a baby by cutting
through the abdomen of the mother) was apparently first described as “a section”
in 1923 although “a Caesar” seems to be the preferred modern medical
slang. The operation had first been
documented in the 1530s and the name was based on that supposedly being the
method by which Julius Caesar (100-44 BC; Roman general and dictator of Rome
49-44 BC) was delivered. Modern thought
has rejected that notion and the legend thus also accounts for the historic
tracing of his cognomen to the Latin caesus,
past participle of caedere (to cut). If there’s any basis to this, it may have
been an ancestor who was so born because Caesar's mother lived to see his adulthood
and there’s no record of any woman in antiquity surviving the procedure which
was performed usually when the mother had already died. Modern medical analysts concur with the improbability
of the link and the first known attempt to on a live woman was in the early
sixteenth century and as late as the 1800s, before antiseptics and blood
transfusions were routinely available, there was a 50% mortality rate.
