Ultimate origin
Latin (lātus)

Pronunciation

  • IPA (Classical): [diːˈɫaː.toː][1]
  • IPA (Ecclesiastical): [diˈlaː.to][1]

Forms

dīlātō (present infinitive dīlātāre, perfect active dīlātāvī, supine dīlātātum); first conjugation[1]

Etymology

The OLD, Gaffiot and Etymonline derive it from dis- “apart” and lātus “wide” with the verb suffix -ō, and Lewis & Short and the Thesaurus take it as a frequentative of differō, participle ⟨dīlātus⟩.[2][3][4][5][6][1]

Earliest recorded meaning

The OLD's earliest citations are from Cicero.[2] Köbler dates Cicero 81–43 BC.[7]

Semantic evolution

It meant to make wider, expand, spread, dilate, as in Cicero's stomachī partēs dīlātantur, and figuratively to swell with self-importance; to extend non-physical things over a wider area; and to express more fully, dilate upon, as in Cicero.[2][3]

In Ecclesiastical Latin it meant to extend, enlarge, open wide.[8] English dilate (late 14th century) first meant “to speak at length”; the sense “to expand” is from the early 15th century.[4]
