What does attested mean?
Attested is the past tense and past participle of the verb "attest," which means to affirm the truth or genuineness of something, whether by giving firsthand evidence, serving as proof itself, or certifying a document formally as a witness. A signature on a will may be attested by two witnesses; archaeological finds attest to the sophistication of an ancient civilization. Used adjectivally, "attested" describes anything verified by reliable evidence: scholars speak of the earliest attested occurrence of a word, meaning the first time it actually appears in surviving records rather than being reconstructed hypothetically. The word derives from Latin testis, meaning "witness," the same root that gives us testify, testimony, and testament. Formal rather than conversational in tone, it appears most often in legal, academic, and historical writing, where precision about what can be proven matters most.
Past tense and past participle of attest: to have provided evidence of, borne witness to, or formally certified the truth of something.
"Colleagues attested to her integrity throughout the investigation."
Often followed by "to" when referring to personal qualities or claims (attest to), or used transitively when referring to documents and facts.
Verified or established as genuine or true by documentary or other reliable evidence.
"The dictionary lists only historically attested spellings of the word."
Frequent in linguistics, where an attested form contrasts with a reconstructed or hypothetical one.
Every time you say "testify" or read a "testament," you're echoing the same Latin root that lives inside "attested" — testis, the Latin word for witness.

Etymology of attested
Attested comes from the verb "attest," borrowed into English from Latin attestari, formed from ad- ("toward") plus testari ("to bear witness"), itself derived from testis, meaning "witness." The same root produced English testify, testimony, testament, and intestate, all sharing the core idea of witnessing. "Attest" entered English around the late sixteenth century, and its participial forms have been in continuous use since then, particularly in legal certification and scholarly citation of evidence.

How attested is actually used
In formal and legal contexts, "attested" carries weight: an attested document has been signed in the presence of a witness who certifies its validity. In historical linguistics, an "attested" form is one actually recorded in written sources, as opposed to a reconstructed one. The stress shifts subtly between uses: as the verb form it is /əˈtɛstɪd/ with two syllables after the stressed vowel sounding alike, but as an attributive adjective some speakers give it a fuller pronunciation. It is a formal register word, uncommon in casual speech.
