Which type of grammatical knowledge does the following statement mean ?

Knowledge about the form, describing it and applying it in limited practice.

The correct answer is Declarative knowledge.

Explanation:

In language learning and grammar acquisition, knowledge is generally divided into two main types: declarative knowledge and procedural knowledge.

1. Declarative Knowledge:
Declarative knowledge refers to "knowing about" something. In terms of grammar, it involves explicit knowledge of grammatical rules, forms, structures, and terminology. It means being able to describe how a rule works and apply it consciously during controlled or limited practice exercises (such as fill-in-the-blanks or explicit rule explanations).

2. Procedural Knowledge:
Procedural knowledge refers to "knowing how" to do something. It is implicit knowledge that enables a learner to use language fluently, automatically, and spontaneously in communication without necessarily reflecting on the underlying grammar rules.

Since the given statement specifically mentions "Knowledge about the form, describing it and applying it in limited practice," it directly describes Declarative knowledge.
