Opposition to or resistance against combining different elements, groups, or things together.
From anti- (against) + combination (from Latin combinare, to join together). The prefix anti- became productive in English scientific and political terminology in the 17th-18th centuries, allowing speakers to quickly express opposition to existing concepts.
This word reveals how English lets us create 'instant opposites' with the prefix anti-, but anticombination is so specific it's almost never used anymore—it was more common in 19th-century industrial and chemical contexts when people needed to debate whether mixing things was always a good idea.
