Usage Note

Common Mistakes

He did it without any unaided help.
He did it unaided.
unaided already means 'without help'; adding 'without any help' creates redundancy.
She finished the race unaidedly.
She finished the race unaided.
unaided is an adjective, not an adverb; unaidedly is not standard English.

Sense: adjective/1

While unaided focuses on the absence of external help, alone emphasises physical solitude — someone can be alone but still receive help later. Independently is the closest formal equivalent, often used for operational or financial autonomy rather than a single act. Single-handedly carries a dramatic, admiring tone, suggesting the task normally requires a team. By oneself is the most natural everyday choice: 'She built the bookshelf by herself' sounds more casual than 'She built it unaided.' Use unaided when you want to stress that no tool, person, or system provided assistance — for example, 'He completed the project unaided' highlights self-reliance, whereas 'He completed it alone' may simply mean nobody else was present.

Etymology

LatinFrenchEnglish

Formed in the late 16th century by adding the negative prefix un- to the past participle aided, from the verb aid, which entered English through Old French aider, from Latin adiūtāre, a frequentative of adiuvāre (to give help).
