disseminate (v.)

1640s, "a spreading abroad (opinion, information, etc.) for acceptance," from Latin disseminationem (nominative disseminatio) "a scattering of seed, a sowing," noun of action from past-participle stem of disseminare (see disseminate). Or perhaps a native noun formation from disseminate. The figurative sense in English is earlier than the literal one of "act of sowing or scattering seed for propagation."

word-forming element of Latin origin meaning 1. "lack of, not" (as in dishonest); 2. "opposite of, do the opposite of" (as in disallow); 3. "apart, away" (as in discard), from Old French des- or directly from Latin dis- "apart, asunder, in a different direction, between," figuratively "not, un-," also "exceedingly, utterly." Assimilated as dif- before -f- and to di- before most voiced consonants.

The Latin prefix is from PIE *dis- "apart, asunder" (source also of Old English te-, Old Saxon ti-, Old High German ze-, German zer-). The PIE root is a secondary form of *dwis- and thus is related to Latin bis "twice" (originally *dvis) and to duo, on notion of "two ways, in twain" (hence "apart, asunder").

In classical Latin, dis- paralleled de- and had much the same meaning, but in Late Latin dis- came to be the favored form and this passed into Old French as des-, the form used for compound words formed in Old French, where it increasingly had a privative sense ("not"). In English, many of these words eventually were altered back to dis-, while in French many have been altered back to de-. The usual confusion prevails.

As a living prefix in English, it reverses or negatives what it is affixed to. Sometimes, as in Italian, it is reduced to s- (as in spend, splay, sport, sdain for disdain, and the surnames Spencer and Spence).

Proto-Indo-European root meaning "to sow." 

It forms all or part of: disseminate; inseminate; seed; seme (adj.); semen; seminal; seminar; seminary; semination; sinsemilla; sow (v.); season.

It is the hypothetical source of/evidence for its existence is provided by: Latin serere "to sow;" Old Church Slavonic sejo, sejati; Lithuanian sju, sti "to sow;" Old English sawan "to sow;" Old Prussian semen "seed," Lithuanian smenys "seed of flax," Old Church Slavonic seme, Old High German samo, German Same; Old English sed, sd "that which may be sown; an individual grain of seed."
