Questions & Answers about Él iba al kiosco en ese vecindario.
Why is the verb iba here instead of fue?
iba is the imperfect tense of the irregular verb ir (to go). We use the imperfect here to talk about a habitual or repeated action in the past, which is why it translates perfectly to 'used to go.' If you used the preterite fue, it would mean he went to the kiosk just once on a specific, completed occasion.
Why does it say al instead of a el kiosco?
Whenever the preposition a (to) sits right next to the masculine word for 'the' (el), they must combine to form the contraction al. This is a strict rule in Spanish, so you will never say or write a el.
I noticed the word kiosco uses a 'k'. Isn't that unusual in Spanish?
Could I use aquel instead of ese for 'that neighborhood'?
You could, but it changes the feeling of distance! Ese means 'that', but usually implies the neighborhood is somewhat close to the speaker, or was just mentioned in conversation. Aquel means 'that one way over there' and emphasizes that the neighborhood is far away in physical distance or distant past memory.
