Losing Your First Language: Portuguese

From Face[t]s of First Language Loss, by Sandra G. Kouritzin (Routledge, 1999), pp. 164-165:

After immigrating to Toronto from Portugal at the age of 1 or 2, Michael didn't learn to speak English until he began Grade 1. When he started school, it became obvious to his teacher that Michael couldn't speak English very well, and so she encouraged his parents to speak to him in that language at home. They tried, but by the time Michael was in Grade 3 and able to function well in school, they reverted to Portuguese in the home. The pattern was well-established however, and Michael continued to reply to them in English.

Apart from his language difficulties, Michael doesn't recall much of his early years of school except that he was in trouble a lot. He "spent a lot of time in the corner" (November 17th, 1995, p. 1), which he attributes to "language issues," and to the fact that he didn't get a lot of support at school. Later, his language issues were multiplied when, during puberty, he simultaneously returned to Portugal for a visit, and also began having speech difficulty when his voice started changing. According to his speech therapist, he began using his false vocal chords; he began feeling very self-conscious using the English language. When he visited Portugal during the summer vacation, he began to feel more comfortable around the Portuguese language, and, at the same time, he stopped using his false vocal chords. It is a chicken-and-egg question whether he feels more comfortable with the sounds and rhythm of Portuguese than with English because his language difficulty was solved in Portugal, or if his language difficulty was solved in Portugal because he felt more comfortable with the language. Either way, it is a moot point; he can no longer speak the language, even having difficulty in retrieving single words.
