Questions & Answers about Por supuesto que quiero ir.
Why is there a "que" after "por supuesto"? We don't say "of course that" in English.
When expressions of certainty like por supuesto (of course) or claro (clearly) are immediately followed by a conjugated verb (like quiero), you must connect them with que.
How does "por supuesto que" compare to "a lo mejor" when choosing the verb mood?
They both use the indicative mood (quiero rather than the subjunctive quiera), but for different reasons. Por supuesto que uses it because it declares a certain fact. A lo mejor is a special phrase that always takes the indicative, even though it expresses uncertainty.
What does the word "supuesto" literally mean on its own?
Supuesto is the irregular past participle of the verb suponer (to suppose). Literally, por supuesto means "for supposed" or "taken for granted," which is why it translates perfectly to "of course."
Why isn't there a preposition between "quiero" and "ir"?
The verb querer (to want) connects directly to an infinitive verb without needing a preposition like a or de in between. Just like poder (can) and deber (must), you simply place the infinitive right after it.
