Inclinación de los adverbios
Re adverbios: "Unlike adjectives, however, they do not change according to gender or number, making them invariable." Es decir que la siguiente frase es correcta? Mi hermana estaba sentado.

Sentado modifies the noun hermana, not the verb estaba, so it is being used as an adjective, and should therefore be sentada.
Let´s first look at what an adverb is. The beginning prefix ad refers to the word adjective. A verb is an action. So an adverb is an adjective that describes some sort of action. In english, we commonly see adverbs ending in -ly. Example: He eats slowly. The eat is getting modified by the adjective slow.
In spanish, adverbs are formed by the FEMININE form of any adjective, and then adding the suffix -mente.
Let´s look at the adjective rápido. The feminine form is rápida right? You then add the -mente suffix to the end and you get, rápidamente. Él come rápidamente.
Adverbs can never be formed in spanish with the masculine form, that is, you´ll never see something like rápidomente. So yes, adverbs are definitely invariable as the formula to create adverbs never changes in either gender or number.
Hope this helps!
