    of documents or signatures created illegally

Common Mistakes

The painting is very authentic.
The painting is authentic.
'authentic' usually does not take 'very' because it describes a yes/no fact, not a quality on a scale.

2. Not the original itself, but made or done in a way that closely captures the loo

2.adjectiveC1
Definition

Not the original itself, but made or done in a way that closely captures the look, taste, or feel of a particular tradition, place, or time period — for example, food cooked the old village way, or a film set built to match an exact decade.

Example

Antonyms

Common Mistakes

I want to learn authentic English from a book.
I want to learn natural English from real conversations.
'authentic' here suggests a copy that imitates an original, which sounds odd applied to a living language; use 'natural' or 'real' instead.

'news' is uncountable; use a countable noun like report, article, or account.

Sense: adjective/1

All four words say that something is not fake, but they differ in feel and use. 'Real' is the everyday choice and works in any register: 'a real diamond'. 'Genuine' is slightly more formal and adds a sense of honest origin: 'genuine leather', 'a genuine smile'. 'Authentic' is the most formal of the four and usually appears when someone has looked carefully at the item — examined a painting, checked a passport, tested a signature — so it suggests verification: 'an authentic Van Gogh'. 'Bona fide' is Latin-rooted, often used in legal, academic, or business writing about people or claims: 'a bona fide buyer', 'a bona fide refugee'. Quick test: at a market you might shout 'These watches are real!', but a museum label will say 'authentic 18th-century clock'.

Etymology

GreekLate LatinOld FrenchMiddle EnglishEnglish

The word travelled into English in the 1300s through Old French 'autentique', which itself came from Late Latin 'authenticus'. The Latin form was borrowed from Greek 'authentikos', meaning 'original' or 'first-hand', built on 'authentes' — a person acting on their own authority. Early English uses described written documents whose authority was beyond doubt; the modern senses about objects, accounts, and faithful copies grew out of that core idea of something being trustworthy at its source.
