A British playwright whose gifts for finding the ominous in the everyday and the noise within silence made him the most influential and imitated dramatist of his generation.  In more than 30 plays — written between 1957 and 2000 and including masterworks like “The Birthday Party,” “The Caretaker,” “The Homecoming” and “Betrayal” — Mr. Pinter captured the anxiety and ambiguity of life in the second half of the 20th century with terse, hypnotic dialogue filled with gaping pauses and the prospect of imminent violence.

Along with another Nobel winner, Samuel Beckett, his friend and mentor, Mr. Pinter became one of the few modern playwrights whose names instantly evoke a sensibility. The adjective Pinteresque has become part of the cultural vocabulary as a byword for strong and unspecified menace.

An actor, essayist, screenwriter, poet and director as well as a dramatist, Mr. Pinter was also publicly outspoken in his views on repression and censorship, at home and abroad. His political views were implicit in much of his work. Though his plays deal with the slipperiness of memory and human character, they are also almost always about the struggle for power.

The dynamic in his work is rooted in battles for control, turf wars waged in locations that range from working-class boarding houses (in his first produced play, “The Room,” from 1957) to upscale restaurants (the setting for “Celebration,” staged in 2000). His plays often take place in a single, increasingly claustrophobic room, where conversation is a minefield and even innocuous-seeming words can wound.

But while Mr. Pinter’s linguistic agility turned simple, sometimes obscene, words into dark, glittering and often mordantly funny poetry, it is what comes between the words that he is most famous for. And the stage direction “pause” would haunt him throughout his career.

Intended as an instructive note to actors, the Pinter pause was a space for emphasis and breathing room. But it could also be as threatening as a raised fist. Mr. Pinter said that writing the word “pause” into his first play was “a fatal error.” It is certainly the aspect of his writing that has been most parodied. But no other playwright has consistently used pauses with such rhythmic assurance and to such fine-tuned manipulative effect.

Though often grouped with Beckett and others as a practitioner of Theater of the Absurd, Mr. Pinter considered himself a realist. In 1962 he said the context of his plays was always “concrete and particular.” He never found a need to alter that assessment.

Few writers have been so consistent over so many years in the tone and execution of their work.
