Due to the nature of pseudo-prepositions as mentioned above, teachers often
find it hard to introduce these prepositions to ESL/EFL learners. No rules can be
stated, nor will explicit instruction fulfill the learners’ needs and help them to acquire
these prepositions. For this reason, providing the learners with a great number of
enhanced instances of prepositional uses to allow the learners to get as much exposure
to the target features as possible may help draw the learners’ attention to these
features (Kao, 2001) and may eventually lead to the acquisition of these prepositions.
Furthermore, encouraging students to notice these linguistic features and raising their
consciousness of the existence of these features may help strengthen their learning.
This research was then conducted to investigate the effects of input enhancement on
the acquisition of English pseudo-prepositions used after verbs and adjectives of Thai
college students.
