Frequently Asked Questions
Can 'lo que' and 'lo + adjective' ever be interchangeable?
Rarely. While 'Lo importante es...' and 'Lo que importa es...' have very similar meanings, they are grammatically different. The first uses an adjective, the second uses a verb. In most cases, you must choose one based on whether you are referring to a quality (lo + adj) or an action/idea (lo que).
Is 'lo' here the same as the direct object pronoun 'lo'?
No, it's a different 'lo'! This is the 'neuter article lo', which is used to turn adjectives or adverbs into abstract nouns. The direct object 'lo' means 'him' or 'it' and replaces a masculine noun, like in 'Lo vi ayer' (I saw him yesterday).
