Also called: 2, 4-D
Word origin
[di-1 + chloro-2 + phen- + oxy-2 + acetic acid]di- is a prefix occurring in loanwords from Greek, where it meant “two,” “twice,” “double”(diphthong). On this model, di- is freely used in the formation of compound words (dicotyledon; dipolar) and in chemical terms (diatomic; disulfide); oxy- is a combining form representing oxygen in compound words, sometimes as an equivalent of hydroxy-. Other words that use the affix oxy- include: alkoxy, epoxy, oxyacetylene, oxymorphone, oxysalt
