“Latin quaere was the imperative of quaerere — to seek or to ask. It was used at the end of legal documents to mark unresolved questions: 'Query: is this valid?' It never imagined databases.”
Latin quaerere meant to seek, ask, or inquire. Its imperative quaere — 'ask,' 'inquire' — appeared at the end of legal and scholarly texts to mark a question requiring investigation. The verb gave English query (a question), inquiry, require, acquire, and question itself via French. The root expressed active seeking: not passive receipt, but purposeful search.
English lawyers and scholars used 'query' from the 17th century as a noun for a question, especially one formally put to an authority. The journalist's query to a source, the reader's query to a publisher — these preserved the legal register. A query was a pointed question requiring an answer.
When relational databases appeared in the 1970s — particularly IBM's System R implementing Edgar Codd's relational model — engineers needed a term for the operation of asking a database a question. Structured Query Language (SQL), developed at IBM in 1974–1979, named itself after the Latin legal term. A database query was a formal question put to a system of records: exactly what the legal quaere described.
Today query appears in every web search, every database operation, every API call. Google processes approximately 8.5 billion queries per day. Each one is a quaere — a pointed question requiring an answer — put not to a judge or a publisher but to an index of the world's information.

Every Google search is a Roman legal question. Quaere — ask this — was written at the margins of documents where the law had not yet settled. The database query has the same character: a formal question put to a body of organized information, expecting a structured answer.
The database does not guarantee truth. Neither did the Roman record-keeper. Both just return what is found.
