This same issue was asked 5 years ago, and a new specific lesson would be helpful. (more than the current article on neutral lo)
Here is what I asked ChatGPT
______________________
tell me more about the use of "lo" in "lo suficiente" and "lo habitual", with grammar explanation and more examples of both
ChatGPT said:
The word "lo" in phrases like "lo suficiente" and "lo habitual" serves as a neutral article that turns adjectives, adverbs, or phrases into abstract nouns. This structure is often used to express qualities or degrees of something in a general, impersonal way.
Explanation of "lo" in these phrases:
Lo suficiente: Here, "lo" makes the adjective "suficiente" (sufficient) into a concept or a general idea. Instead of referring to something specific, "lo suficiente" means "enough" in a more abstract way, as in "the sufficient amount."
Example: No hemos hecho lo suficiente para resolver el problema.
(We haven't done enough to solve the problem.)
Lo habitual: Similarly, "lo" turns the adjective "habitual" (usual) into an abstract noun, referring to "what is usual" or "the usual thing."
Example: Llegó tarde, como lo habitual.
(He arrived late, as usual.)
