Forms

indagine f (plural indagini)[1]

Etymology

It is a learned word, borrowed from Latin indāgō (“a ring of hunters or nets; a search”).[2][3][4][5] The Latin noun first meant a hunt in which the game was surrounded and driven into nets, and then a search or investigation.[3][5][6] It is formed from indu-, an old form of in- (“in”), and the root of agō (“to drive”) with a lengthened vowel, as in ambāgēs (“windings”).[3][7][1] The same prefix is in the words that gave indigeno, indigente, indole and industria.[3]

Sabatini–Coletti, Zingarelli and Gabrielli derive the Latin noun from the verb that gave indagare, but the OLD makes the verb a derivative of the noun.[8][9][10][7]

Earliest recorded meaning

The TLIO has one early example, in the Rime of the Sienese Domenico da Monticchiello (1358), with the sense “an order to do something”.[11] DELI's first record is in Galileo (1630–1631), for a study or analysis.[2][5] Zingarelli dates the word to 1480.[9]

Semantic evolution

Galileo's Dialogo discusses an author's dodici indagini (“twelve inquiries”) into the new star of 1572.[12][13] DELI dates the sense “careful, systematic research” to Metastasio in 1770, and “investigation” to Carducci in 1861.[2] The indagine conoscitiva, an inquiry held by a parliamentary committee to gather information, is recorded in 1973.[2]

In modern law the plural indagini is the investigation by the police and the judiciary, and the indagini preliminari are those that decide whether a prosecution is brought.[5][6] The word is also used for market research and statistical surveys.[5][6]
