Etymology

mildew = mil<honey> + dew<moisture>

  • mil<honey>: From Old English milde, meaning "honey" (related to sweetness or sticky substances).
  • dew<moisture>: From Old English dēaw, meaning "moisture" or "condensation."

Etymology Origin:
The word "mildew" originated in Old English as mildeaw, combining mil (honey) and dew (moisture). It originally described a sticky, honey-like substance caused by dampness, later evolving to refer specifically to fungal growth. The connection to "honey" reflects the appearance of early mildew, which resembled a sugary or sticky deposit. Over time, the meaning narrowed to its current fungal sense.
