It is not a conscious process. As you know, from your own language, we do not think in terms of grammatic structure. We understand the meaning of what we hear or read as a whole. nevertheless, when the structure is faulty, we hear the mistake as well.Originally Posted by Taka
It is common for learners to ask a question beginning with: I am confusing. We know what they meant, but we still hear the mistake. Most people don't say "He used a progressive verb when he intended a predicate nominative."
When it comes to pronouns, we sometimes confuse each other. Imagine a sentence in which a person is talking about two women. Afetr a while, if the speaker/writer keeps using she and her, it will be unclear which woman he is talking about. "It" can be just as confusing.
