This scoping review studies the role of grammar in second language teaching and learning. This scoping review mainly directs to synthesizing relevant studies and literature on acquiring grammar and looking for strategies for achieving it. Grammar acquisition requires the subconscious mind of accepting grammatical knowledge that is then confined and used in communication. Its implicit nature makes it hard to conduct studies about it, and there is a need for more information that can help contribute to the existing knowledge about it. Hence, this scoping review gathered and scrutinized recent and relevant papers from various databases. The collected papers consist of qualitative and quantitative studies. Many language teachers agree that pedagogic grammar is crucial in second language acquisition. Hence, this paper analyzes recent and relevant papers about grammar acquisition. This scoping review found out that the importance of studies about grammar acquisition should not be forsaken; thus, more investigations must be done to contribute to the already existing knowledge. A byproduct of these studies can lead to better strategies for promoting grammar acquisition to language learners. Hence, the amelioration of Second Language Learning and Second Language Teaching is inevitable.
