Latin insero

Pronunciation

  • Classical: [ˈĩː.sɛ.roː][1]
  • Ecclesiastical: [ˈin.se.ro][1]

Forms

īnserō (present infinitive īnserere, perfect active īnsēvī, supine īnsitum); third conjugation[1]

Etymology

The verb “sow, graft” is formed from Latin in- + serō (“to sow”).[2][3][1] De Vaan traces this serō to Proto-Italic *si-se/o- (“to sow”) and the reduplicated present Proto-Indo-European *si-sh₁-e/o- (“to sow”), from Proto-Indo-European *seh₁-; cognate with Lithuanian sėti (“to sow”) and Gothic 𐍃𐌰𐌹𐌰𐌽 (saian, “to sow”).[4]

Earliest recorded meaning

Cato, De agri cultura, of olive cuttings set in the nursery: eās sīc īnseritō, “plant them like this”.[2][5]

Semantic evolution

It is to sow or plant, and to graft a scion on a tree: Cato tells how to take a shoot of the kind one wishes to graft, Varro grafts a good pear on a wild one, and Virgil says wild trees lose their wild nature when grafted.[2][3] Figuratively it is to implant or root: Cicero says eloquence plants new opinions and pulls out those already implanted.[2] Its participle īnsitus is “inborn”.[3]

Church Latin glosses it “implant, ingraft, insert”.[6]

Timeline

  • 234–149 BC – Cato of planting and grafting.[2][5]
  • 116–27 BC – Varro of grafting pears.[3][5]
  • 81–43 BC – Cicero of implanting opinions.[2][5]

Meanings

Verb

  1. To sow or plant (in).[2][1]
  2. To graft (a scion; a tree).[2][3][6]
  3. (figuratively) To implant, fix.[2][6]

Pronunciation

  • Classical: [ˈĩː.sɛ.roː][1]
  • Ecclesiastical: [ˈin.se.ro][1]

Forms

īnserō (present infinitive īnserere, perfect active īnseruī, supine īnsertum); third conjugation[1] Livius Andronicus has the old passive īnserinuntur.[2][4]

Etymology

The verb “insert” is formed from Latin in- + serō (“to join, string together”).[2][3][7] De Vaan traces this serō to Proto-Italic *sere/o- and Proto-Indo-European *ser- (“to thread, tie together”), cognate with Ancient Greek εἴρω (eírō, “to fasten together”) and Oscan aserum (“to lay on”).[4]

Earliest recorded meaning

De Vaan's first author is Livius Andronicus.[4]

Semantic evolution

It is to put or thrust in, to insert: Cicero, translating Aeschylus, has wedges driven in that break the limbs, and Ovid's oculōs īnserere is to look into something.[2] It is also to attach or join, and manūs īnserere is to lay hands on.[2] It is to put among others or include, as Horace's boy who could be set among a chorus of girls, and to insert into a book or speech, as Livy's speaker who inserts complaints and demands.[2]

Church Latin glosses it “introduce, enroll, insert, intrude”.[6] English insert (1520s) comes from its participle īnsertus.[7]

Timeline

  • 280/260–before 200 BC – Livius Andronicus.[4][5]
  • 81–43 BC – Cicero of driving in wedges.[2][5]
  • 65–8 BC – Horace of including among others.[2][5]
  • 59 BC–17 AD – Livy of inserting in a speech.[2][5]
  • 1520s – English insert.[7]

Meanings

Verb

  1. To put in, insert, introduce.[2][1][6]
  2. To attach, join, manūs īnserere, to lay hands on.[2]
  3. To place among, include; to insert (in a book or speech).[2][1][6]
