Regarding point c in the article: ‘c) as the neuter direct object lo, such as in the sentence quiero comprarlo, “I want to buy it.”‘
In my understanding, the -lo in this case is one of the rare occurrences of the, grammatically speaking, nearly extinct accusative case that is employed when a direct object is used. Examples:
1. El anillo es muy hermoso. Quiero comprarlo.
2. La lechuga es muy barata. Quiero comprarla.
Good point. Actually, the -lo there could be either masculine or neuter, depending on whether you know the name of what you want to buy.
