Phoocharoensil (2013) studied the influence of learners’ mother tongue on their acquisition of English collocations. The research found that the native language (L1) plays a significant role in the participants’ collocation learning as it is regarded as a primary learning strategy on which they depend. Yumanee (2012) discovered that there were existed other potential factors that contributed to the high degree of collocational errors such as the synonymy strategy, the learners’ creative invention and the strategy of analogy, the paraphrasing strategy, and low knowledge of collocational skills. Besides, Boonyasaquan (2006) and Koya (2003) showed that the native language or L1 evidently has a great impact on high-proficiency learners’ use of English collocations found support for some past studies. Lewis (2000) said that collocation, in other words, exists in statistically significant manners. Consequently, teaching how to increase collocational skills is worth the effort because collocation is the smart way to sound more natural and fluent like a native speaker.
