pulsatev.

Brit.

/pʌlˈseɪt/, U.S.

/ˈpəlˌseɪt/

Origin: A borrowing from Latin. Etymons: Latin pulsāt-, pulsāre.

Etymology: < classical Latin pulsāt-, past participial stem (see -ate suffix³) of pulsāre pulse v. Compare earlier pulse v., pulsative adj., pulsation n., pulsator n.With sense 3 compare earlier pulsator n. 3b. Stress on the first syllable was apparently usual in British English as well as U.S. English until the early 20th cent., although there is also evidence for stress on the second syllable in the late 19th cent. N.E.D. (1909) still gives only the pronunciation with stress on the first syllable but H. Michaelis & D. Jones Phonetic Dict. Eng. Lang. (1913) already gives stress on the second syllable as the dominant pronunciation.
