Canaanite Shift

In historical linguistics, the Canaanite shift is a sound change that took place in the Canaanite dialects, which belong to the Northwest Semitic branch of the Semitic languages family. This sound change caused Proto-NW-Semitic *ā (long a) to turn into ō (long o) in Proto-Canaanite. It accounts, for example, for the difference between the second vowel of Hebrew שלום (šalom, Tiberian šālōm) and its Arabic cognate سلام (salām). The original word was probably *šalām-, with the ā preserved in Arabic, but transformed into ō in Hebrew. The change is attested in records from the Amarna period, dating it to the mid-2nd millennium BCE.

Famous quotes containing the word shift:

    The shift from the perception of the child as innocent to the perception of the child as competent has greatly increased the demands on contemporary children for maturity, for participating in competitive sports, for early academic achievement, and for protecting themselves against adults who might do them harm. While children might be able to cope with any one of those demands taken singly, taken together they often exceed children’s adaptive capacity.
    David Elkind (20th century)
