These neuter relative pronouns refer to a situation, an unknown antecedent or concept, not a specific masculine / feminine noun or pronoun
I am comfortable with the following usage
Sé todo lo que haces para mejorar.I know everything that you do to improve.
Dicen que soy guapa, lo que es verdad. They say I'm pretty,which is true.
However, there are some examples where the antecedent is a noun in which lo que/lo cual is used but I feel as though que should have been used instead. i.e I am having trouble understanding whether the antecedent is specific or not.
Tengo una manta de sobra, lo cual no necesito.I have an extra blanket, which I don't need.
lo cual is used when the antecedent is not specific so why is it being used here? isn't la manta a specific antecedent? shouldn't que be used here?
Panamá tiene acceso a dos océanos, lo que facilita su economía.Panama has access to two oceans, which facilitates its economy.
lo que is used here since the something being mentioned is acceso a dos océanos not the dos oéanos.
However, if the something being mentioned was the dos océanos then que would have been used
Panamá tiene dos océanos, que facilita su economía. Panama has to two oceans, which facilitates its economy.
Am I right?
Hay nubes, lo que indica lluvia. There are clouds, which indicates rain.
isn't nubes, the something being mentioned a specific feminine noun so why isn't que being used
or is it that there are clouds is not specific as opposed to these are the clouds as in the following sentence?
estas son las nubes que parecen elefantes these are the clouds that look like elephants
Assuming "These are + noun..." is specific and "There are + noun" isn't specific, then what about
estas son las manzanas... vs estas son las manzanas...
or even the following
una manzana que es roja... vs la manzana que es roja....
since la is specific and una isn't
or what about people - I know quien/es is used for people but if "there are clouds" isn't specific then "there are people" isn't specific also
Estas son las personas que están tristes these are the people who are sad.
Hay personas lo que están tristes there are people who are sad
