Elide
Etymology
From Latin elidere, "to strike out, force out," from ex- ("out") plus laedere, "to strike, hurt." In linguistics it names the dropping of a sound, as when "do not" becomes "don’t." The broader modern use — to elide a distinction or a fact — extends that idea of striking something out so it disappears from view.
verb · /ih-LYDE/
To leave out, omit, or blur over something — a sound, a detail, or a distinction.
What it names
The word for quietly dropping something out — slurring two ideas together, or skipping a step so smoothly the gap goes unnoticed.
Example
The summary elided the messy middle years, jumping from the founding straight to the triumph.
Related idea
Omit is a plain leaving-out; elide often implies smoothing over — merging or glossing so the omission is barely felt.
