Fact keeps the -ct- cluster that marks a word taken straight from Latin rather than worn down through French. It is Latin factum, "a thing done," the neuter past participle of facere, "to do" — the same root as in factory, manufacture, affect and perfect.
English has the French version of the same word too. Old French fait, from the identical Latin source, gave English feat. So fact and feat are one word borrowed twice, and their meanings show the difference: the Latin borrowing became abstract and intellectual, the French one stayed concrete and heroic. The English senses moved a long way. In the 1500s and 1600s a fact usually meant a deed, and commonly an evil deed or a crime — a sense preserved in the legal phrase after the fact. The modern empirical sense, a thing known to be true, came later.
fact
(n.)
1530s, "action, a thing performed, anything done, a deed," good or evil but in 16c.-17c. commonly "evil deed, crime;" from Latin
factum
"an event, occurrence, deed, achievement," in Medieval Latin also "state, condition, circumstance" (source also of Old French
fait
, Spanish
hecho
, Italian
fatto
), etymologically "a thing done," noun use of neuter of
factus
, past participle of
facere
"to do" (from PIE root
*dhe-
"to set, put").
An earlier adaptation of the Old French word that also became
feat
. The older senses are mostly obsolete but somewhat preserved in such phrases as
after the fact
, originally legal, "after the crime." Also compare
matter-of-fact
.
The modern, empirical, sense of "thing known to be true, a real state of things, what has really occurred or is actually the case," as distinguished from
statement
or
belief
, is from 1630s, from the notion of "something that has actually occurred." The particular concept of the scientific, empirical fact ("a truth known by observation or authentic testimony") emerged in English 1660s, via Hooke, Boyle, etc., in The Royal Society, as part of the creation of the modern vocabulary of knowledge (along with
theory
,
hypothesis
, etc.); in early 18c. it was associated with the philosophical writings of Hume. Middle English thus lacked the noun and the idea of it; the closest expression being perhaps
thing proved
(c.1500).
Hence
facts
"real state of things;"
in fact
"in reality" (1707). By 1729,
fact
was being used of "something presented as a fact but which might be or is false."
By
fact
is also often meant a true statement, a truth, or truth in general ; but this seems to be a mere inexactness of language ....
Fact
, as being special, is sometimes opposed to
truth
, as being universal ; and in such cases there is an implication that facts are minute matters ascertained by research, and often inferior in their importance for the formation of general opinions, or for the general description of phenomena, to other matters which are of familiar experience. [Century Dictionary]
Facts of life
is by 1854 as "the stark realities of existence;" by 1913 it had also acquired a more specific sense of "knowledge of human sexual functions." The alliterative pairing of
facts and figures
for "precise information" is by 1727.
Facts and Figures are the most stubborn Evidences; they neither yield to the most persuasive Eloquence, nor bend to the most imperious Authority. [Abel Boyer, "The Political State of Great Britain," 1727]
