man·i·fes·to | \ ˌma-nə-ˈfe-(ˌ)stō \
plural manifestos or manifestoes
: a written statement declaring publicly the intentions, motives, or views of its issuer
Manifesto is related to manifest, which occurs in English as a noun, verb, and adjective. Of these, the adjective, which means "readily perceived by the senses," is oldest, dating to the 14th century.
Both manifest and manifesto derive from the Latin noun manus ("hand") and -festus, also found in the Latin adjective infestus meaning "hostile, bold, overrun in large numbers."
The Latin festum means "feast" or "celebration"
Manifestoes, in etymology, make the writer's intentions clear for its audience, stirs up trouble in a bold way, and celebrates all of it.
While manifestoes have often served as tools to make absolute claims and dogmatic beliefs, their form is anything but fixed.
