When we are learning something new, e.g., a language, a programming language, math, ... we are in an open receptive mode. The syntax and grammar of what we are learning is often being assimilated into the neurology past critical thinking filters or questions about the presuppositions built into the syntax and grammar of what we are learning. That syntax and grammar then become filters for what we perceive. They also limit the expressibility of what we perceive by the constraints of that same syntax and grammar.
