Grammar gains its prominence in language teaching, particularly in English as a
foreign language (EFL) and English as a second language (ESL), inasmuch as
without a good knowledge of grammar, learners’ language development will be
severely constrained. Practically, in the teaching of grammar, learners are taught
rules of language commonly known as sentence patterns. According to Ur (1999), in
the case of the learners, grammatical rules enable them to know and apply how such
sentence patterns should be put together. The teaching of grammar should also
ultimately centre attention on the way grammatical items or sentence patterns are
correctly used. In other words, teaching grammar should encompass language
structure or sentence patterns, meaning and use.
