Patterns of Misspellings in L2 and L1 English: a View from the ETS Spelling Corpus

This paper presents a study of misspellings, based on annotated data from the ETS Spelling corpus. The corpus consists of 3000 essays written by examinees , native (NS) and non-native speakers (NNS) of English, on the writing sections of GRE® and TOEFL® examinations. We find that the rate of misspelling s decreases as writing proficiency (essay score) incr eases, both in TOEFL and in GRE. Severity of misspellings depends on writing proficiency and not on NS/NNS distinction. Word-length and wordfrequency have strong influences on production of m isspellings, showing patterns associated with proficiency. For word-frequency, there is also a cl ear effect of NS/NNS distinction.
