Yod-coalescence also occurs in some other words where other English variants either resist it or do not call for it, e.g. calcium and Celsius are respectively [ˈkälʃʊm] and [ˈsɛlʃʊs]. For these reasons, the use of yod-coalescence is another case of approximation for aspirated consonants which Philippine languages lack in general in words such as twelve. Yod-retention is usually practiced selectively, similar to the historical mid-Atlantic accent in the U.S., Irish or British and Commonwealth English, and to a lesser extent, some speakers of English in Canada, in certain words such as new(s) but not student.
