This investigation in the field of second language acquisition is mainly concerned with error studies and analyses, having its main emphasis on German learners of English as a second language. This book explores what has already been done in the field of applied linguistics specifically focusing on efforts to prevent German learners of English as a second language making errors, and if there are any particularly frequent errors that can be avoided by means of SLA analysis. Moreover the book throws a glance at the future and attempts to determine what needs to be done in order to minimize German learners' failures in terms of the English language.
