What process involves reverting to earlier syntactical rules and may require reteaching?

The process that involves reverting to earlier syntactical rules and may require reteaching is known as "Simplifier." This concept revolves around the notion that learners, particularly those acquiring a second language, might initially implement more complex language structures but then simplify their language use as they navigate through learning. This simplification may lead to the return to earlier versions of syntax that were previously understood, as learners often rely on the language patterns that feel most comfortable to them.

In this context, reteaching becomes necessary to help the learner move beyond these simplified structures and grasp more advanced syntax. The goal is to support the learner in progressively building their language proficiency, helping them transition from simpler to more complex constructions over time.

In contrast, the other terms relate to different processes. "Reconstructor" suggests building back from knowledge, "Updater" implies incorporating new information, and "Modifier" may refer to changing existing structures without needing the same level of foundational retrieval as simplification does. Understanding these distinctions helps clarify why the simplifying process is critical in the language learning journey.
