Abstract
In foreign language learning, second language learners as well as Native speakers commit mistakes in their attempt to achieve knowledge in the target language. It has been observed that most of the second language learners in this research group commit collocation mistakes. The purpose of the study is to understand the nature of made errors as stumbling blocks to effective pre-Social Media Content Writing. The objective of the investigation is to identify the errors, analyze their structural compositions so as to identify whether there are similarities between students in this regard and to find out whether there are patterns to these kinds of mistakes which will enable the researcher to understand their sources and causes. As a descriptive research, the researcher samples 120 post writing collected from 12 learners of English as a second language.
