In plain English: An ide is an old-fashioned name for a type of fish that lives in freshwater rivers and lakes.
"The old ide swam gracefully through the clear water before diving beneath the surface."
Usage: The ide is a large freshwater fish native to northern Europe and Asia that anglers often target for sport fishing. It belongs to the carp family but is distinct from related species like pike or perch due to its specific habitat in slow-moving rivers and lakes.
A surname, from given names.
"Many members of the Ide family trace their name back to ancestors whose first names began with that letter."
Obsolete form of I'd.
"The editor corrected the obsolete ide to I'd in the manuscript from the eighteenth century."
The word ide comes from the Germanic root found in Swedish and entered English via French as a scientific term for fish species. It originally referred to any member of this group of freshwater fishes rather than having a different meaning today.
