This report deals with sporadic observations on the glottal stop in the English spoken by Finns. The data were collected in connection with two separate studies. An attempt is made to give a description of the factors which may explain the occurrence of glottalization and to outline the method by which the phenomenon will be approached in greater detail in the future. It is felt that the key to the difficulties connected with glottalization is the difference between the Finnish and English concept of the morphophonological word, or, more precisely, the different role assigned to glottalization in these languages. Three groups of 15- and 16-year-old Finnish students of various dialect backgrounds were tested for their pronunciation of Finnish and English. Irrespective of dialect, glottalization was more evident in English than in Finnish. A second test was based on the pronunciation of test sentences by 24 ninth grade pupils from the Ostrobothnian dialect area. From these tests, it may be concluded that: (1) erroneous word-boundary signalling exists with pupils who do well in their language studies as well as those who do not; (2) some students retain features of interference from native language pronunciation even after long exposure to a foreign language; and (3) possibly a student's word-boundary signalling pattern can be attributed to teacher pronunciation.
