摘要:Ever since the first explicit mention of the term ‘conversion’ by Henry Sweet (1891-98), an important number of authors have periodically approached the topic from different perspectives, trying to come to terms with one of the most frequent procedures for word-formation in English. It seems, however, that the interest kindled by the phenomenon runs parallel to the inconsistencies and problems which it poses and, despite the attempts to unify criteria, conversion is still perceived as peculiar compared to other word-formation patterns. In view of the situation, the present work intends to gather a variety of opinions on conversion along with the author’s view of the process.
