Pronunciation

  • Classical: [ɪŋˈɡrɛ.di.ɔr][1]
  • Ecclesiastical: [iŋˈɡrɛː.di.or][1]

Forms

ingredior (present infinitive ingredī, perfect active ingressus sum); third (-iō variant) conjugation, deponent[1] Plautus may have the infinitive ingredīrī, Lucretius splits it (inque gredī); the archaic compound indugredior is found in Lucretius.[2][3][4]

Etymology

It is from Latin in- (“in, into”) + gradior (“to step, walk”), with the vowel weakened in the compound.[2][1][4] De Vaan explains ⟨-gredior⟩ for expected ⟨*-gridior⟩ by analogy with the participle ⟨-gressus⟩, and traces gradior to Proto-Italic *grad-ei-, from a root that Wiktionary gives as Proto-Indo-European *gʰredʰ- (“to step”);[5][1] he compares Old Irish in·greinn (“to chase”).[5]

Earliest recorded meaning

Plautus: ingressus fluvium rapidum, “having gone into a swift river”.[2][6] Ennius has quod iter incipiam ingredī?, “what road shall I start to take?”.[2]

Semantic evolution

Ingredior is to go into or onto a place, properly on foot, and to set out on a road.[2][3] Figuratively it is to enter on a period of office or of life (Sallust: ubi prīmum magistrātum ingressus est) and to begin an undertaking, a speech or a subject (with an infinitive, “to begin to”).[2][1] Used alone it is to walk, move forward (Cicero, of a man who could hardly walk), and to advance to the attack.[2] Döderlein notes that ingredī, like intrāre and introīre, is a literal entering, while inīre is almost always figurative.[7]

In the Bible it is also to go in to a woman.[1] Church Latin glosses it “enter, come in, advance, begin”.[8] English ingredient (early 15th century) and ingress (mid-15th century) come from its present participle and its noun ingressus.[9]
