of one mind; without dissent
"the Senate unanimously approved the bill"
"we voted unanimously"
In a unanimous manner; without objection.
"The committee voted unanimously to approve the new budget proposal."
In plain English: Unanimously means everyone agrees without any disagreement at all.
"The committee voted unanimously to approve the new plan."
Usage: Use unanimously to describe an action where every member of a group agrees, such as when voters approve a motion or jurors reach a verdict. This adverb specifically emphasizes the absence of any dissenting opinions among those involved in the decision.
Unanimously comes from the adjective unanimous, which itself is formed by adding the prefix un- to the Latin word animus, meaning "mind." The suffix -ly was then attached to create an adverb describing actions done with everyone sharing the same mind or opinion.
