Adverb clauses modify adjectives, verbs, and adverbs

An adverb clause is a group of related words that have at least a subject and a verb, which may be dependent or independent (it expresses a complete thought) and whose function is to act as an adverb, that is to say, to modify adjectives, verbs or other adverbs. This type of clauses often answers questions such as "Why?", "How?", "When?", "Where?" and "In what circumstances?".

Here are some examples (The adverb clauses are underlined):

Before going to the party, I visited my old friend Ricardo.

(When did you visit Ricardo? Before going to the party. This clause adds information about WHEN an action took place, meaning that it modifies a verb)

I have three cats because I like their company.

By the time I had arrived, they were eating the cake.

to kill a mockingbird basically is about a lawyer who goes against everything in a racist society like at the time of this novel, to defend a black man accused of sexual abuse. in the bible there are cases like that of joseph, who was accused by the woman of potifar, for a crime similar to that of tim robbinson, of that novel (genesis 39: 1-20). at this point we see that god also provides the escape to joseph, who was accused unjustly, but in his time, and through his attitude, his faith was not shaken, and god provided the solution. the perspective of god also written in the bible and not pay evil with evil. (ephesians 4: 32, 1 thessalonians 5: 15, 1 peter 3: 9). atticus, the lawyer, demonstrated during this lee novel, empathy, love of neighbor, understood the situation of this accused man. he went against everything in that society, and stood in favor of that man, for the injustice committed. this shows the empathy, the love taught by christ, in some passages that speak of love and justice in the sermon of the beatitudes (especially verses 6 and 7 of matthew 5).
