Mainly word ending in "e" are masculine but thats not always the case and then obviously the ones ending in "a" are mainly feminine and "o" is mainly masculine. If you arent sure then you can just take a guess or you can search the word up in a spanish dictionary or on google which is the more modern way. Hope this helps.
Dont use google translate! Its mainly all incorrect and even mixes up languages so if you want to search what a spanish word means then you could use a spanish dictionary or just search the spanish word up and it'll tell you if its masculine or feminine and what it means. Hope this helps.
I typed "una ca" and as I was reaching the L on my keyboard my finger slipped and pressed enter.
The words that end in an "A" are feminine, and practically anything else is masculine, although there are certain exceptions to the rule where you use a feminine article (an, a) or pronoun for a word that would usually be masculine. I can't think of another one off the top of my head but I think that this is one.
I'm pretty sure the only words that can apply to either gender are adjectives. Street is a noun, so it has to be given a gender. I'm not sure why it isn't calla. I just know that if calle was genderless, there would be no way to say the street or a street because you have to say either el or la or un or una. I'm fairly new at speaking Spanish so maybe I'm wrong :D
You can use words that are not in the lessons. For instance, searching synonyms for a word, and using it. That's the whole point here.
If they gave "jirón", it's maybe because you tried to enter "calle", but with a typo and it interpreted your answer differently.
It's only "street" in Peru.
En Perú, los jirones son vías urbanas de poca extensión,
(In Peru, the jirones are urban streets of little expansion.)
So, it doesn't mean streets, but rather small streets it seems.
