To collect the data, the students were assigned a writing test for this study at the very last session of the course. The students were asked to write a topic of 150 words about a place they know, and a person who attends this place. They were inquired to use as much as they can of deictic expressions they have studied in their semantics course. Data were analyzed by using mean scores, standard deviation, t-test and covariance. The findings data analysis revealed that EFL Saudi students were capable to use the target deictic expressions more in syntactic functions than in semantic functions. The results also indicated that there were statistically significant differences between the subjects' representation of the deictic expressions in the syntactic functions and the semantic functions.
