migratev.

Brit.

/mʌɪˈɡreɪt/,

/ˈmʌɪɡreɪt/, U.S.

/ˈmaɪˌɡreɪt/

Origin: A borrowing from Latin. Etymons: Latin migrāt-, migrāre.

Etymology: < classical Latin migrāt-, past participial stem (compare -ate suffix³) of migrāre to change one's residence or position, to move from place to place, to pass into a new condition or form, to move or shift (belongings, etc.), probably ultimately < an extended form of the base of meiere (see mighe v.), mūnis (see common adj.), and mūtāre (see mutate v.); a different extended form of the same base may have given rise to ancient Greek ἀμείβειν to change, exchange.Stress is marked as falling on the first syllable in Webster (1828), and this has remained standard in U.S. pronunciation. Ogilvie (1850) also gives stress on the first syllable, and N.E.D. (1906) gives the pronunciation as (məi·greⁱt) /ˈmaɪɡreɪt/. According to R. Dittes in Englische Studien 73 (1938) pp.49–55, stress in British English moved from the first to the second syllable in the late 19th cent. with the establishment of the verbal suffix -ate (-ate suffix³) with a long vowel; there is some metrical evidence that this shift began in the first half of the 19th cent. Stress is marked on the second syllable in the first edition of D. Jones Eng. Pronouncing Dict. (1917), but stress on the first syllable is still recorded as a less common variant in British usage in the 15th edition (1997).
