1. 1
   adjective

   Made up of parts that are combined and coordinated to function as a single unified whole.

   Similarunified, combined, coordinated, consolidated

   Oppositefragmented, separate, disjointed

   Note

   Unlike the bare participle, this adjective takes degrees. A system can be more integrated or most integrated, and fully integrated stresses that nothing is left out. The parts keep their own identities but are made to work as one. Vitali Vitaliev, writing in RAIL in 2025, credits the Swiss railways' integrated timetable, which joins trains, ferries, cable cars and buses. The racial sense is a narrower use of the same idea.

2. 2
   verb

   Past tense and past participle of integrate.

   The company integrated the new software into its existing systems last year.

   The two departments have been integrated under a single manager.

   Note

   One spelling covers both the simple past (they integrated the teams) and the participle used in perfects and passives (the teams have been integrated). The verb is usually transitive. In the sense of fitting in, it can stand alone or take a reflexive: the newcomers integrated quickly. In mathematics it means finding an integral: she integrated the function over the interval.

3. 3
   adjectiveUS

   Bringing together people of different races in the same schools, neighborhoods, or institutions rather than keeping them separated.

   Like a single garden where many kinds of flowers grow in the same beds rather than separate plots.

   By the 1970s, the city's integrated schools enrolled children from across every part of town.

   She grew up in one of the first integrated neighborhoods in the region.

   Similarmixed, multiracial

   Oppositesegregated

   Note

   Here the word belongs to US usage. It is the adjective that matches the verb's desegregating sense: an integrated school or neighborhood is one that has been desegregated. Outside that setting, a reader may first hear the general "unified whole" sense. Where the meaning could be unclear, let the noun do the work. An integrated school is plainly about who attends it.
