Collocational competence is important part of L2 English amplifier acquisition. This competence entails learners' ability to use the right combination of words with natural-sounding semantic prosody. It is known to be an integral part of mastering pragmatic function of L2 English vocabulary, which also is a challenge for the learners at the same time (Zhang, 2008). Despite the importance, previous studies on ESL/EFL learners' amplifier use lacked empirical evidence and insight about semantic prosody. The purpose of present learner corpora-based study was to fill the existing research gap by finding patterns of amplifiers. Two existing corpora were selected, coded, and analyzed to fulfill this purpose; they are Korean EFL learners and native speakers of English (NE). Results from analysis found Korean learners' overall underuse in amplifiers. Also, frequently occurring amplifier ranks for each corpus differed. Semantic prosody analysis revealed that amplifier associated with dominantly positive connotation were very, really, and highly. Amplifiers associated with dominantly negative connotation were extremely, absolutely, severely, and greatly. Contrast analysis showed that the only amplifier that Koreans and NEs used amplifier to signal same semantic prosody dominantly was severely (negative). Other than that, Koreans and NE showed salient discrepancies in semantic prosody use. The pedagogical implication of the present study is that vocabulary teaching need to include semantic prosody, and the first step will be to conduct ESL/EFL teacher education about it (Zhang, 2009). It's important to remind them of the value of semantic prosody in language communication (S Lee, 2011).
