Questions & Answers about Mi hermano siempre va al gimnasio.
Why does the sentence use 'al' instead of just 'a'?
What verb does 'va' come from?
Can I put 'siempre' somewhere else in the sentence?
Usually, frequency words like siempre (always) go right before the verb, just like in English. So, siempre va is the most natural word order. However, Spanish is quite flexible, so you might also hear it at the very beginning or end of the sentence.
