Subordinate clauses of manner
See also: Conjunción and Conjunction types
In Spanish, subordinate clauses of manner express how something is done; more precisely, how the action in the main clause is done. These clauses depend on the main clause, so they don't make sense on their own.
Let's see some examples with some common manner connectives:
Envié los documentos al cliente, conforme se acordó en la reunión.I sent the documents to the client, following what was agreed in the meeting.
Se puso a bailar flamenco como si lo hubiera hecho toda su vida.He started to flamenco dance as if he had done it all his life.
Some manner clauses use the indicative and some the subjunctive.
