Grammar learning is different from other academic subjects since grammar builds on prior knowledge. L2 learning goes beyond acquisition of linguistic features. The process includes communication, cultural awareness, the ability to compare and contrast L1 and L2, and the use of language skills with academic disciplines Here is a good definition of grammar: Grammar is the structure of a language. It is a set of rules specifying the ways words are inflected (how endings are added to change the meaning) and the ways individual words can be combined into larger units to form phrases, clauses, or sentences (ProLiteracy, 2013).
