Etymology

submerge = sub<under> + merge<dip, sink>

  • sub<under>: From Latin sub, meaning "under, below." Commonly used in English prefixes (e.g., subway, submarine).
  • merge<dip, sink>: From Latin mergere, meaning "to dip, immerse, or plunge." The root appears in words like immerse and emerge.

Etymology Origin:
The word submerge directly combines Latin sub (under) and mergere (to dip), forming a verb that literally means "to plunge under." It entered English in the early 17th century, retaining its original sense of immersion in liquid. Over time, it gained figurative uses, such as "to overwhelm" or "to hide completely," reflecting the idea of being buried beneath something.
