[1875–80; mono- + metallic]This word is first recorded in the period 1875–80. Other words that entered Englishat around the same time include: cross-fertilization, fan-tan, knockabout, slime mold, weekendermono- is a combining form meaning “alone,” “single,” “one” (monogamy); specialized in some scientific terms to denote a monomolecular thickness (monolayer) and adapted in chemistry to apply to compounds containing one atom of a particularelement (monohydrate). Other words that use the affix mono- include: monoacid, monochromatic, monogyny, monohybrid, monorail
