How to write spinnable content? I need to lear so i can write in spanish too.

Hi guys, lately i'm doing a lot of questions, and here is another.
Being natively a spanish speaker i need to post most of the content in spanish, and even if i write something in english for a client, i first write it in spanish, and then send it to a translator to rewrite it in english.

Yesterday i bough a monthly rankerX license and obviously all the content and most of the sites are in english, and all the spin tools i know are also in english, this is a problem for me, so i want to understand how to write content that is spinnable.

So far i undertand this: a phrase to be spinnable needs to have this structure {keyword or phrase|alt keyword or phrase 1|alt keyword or phrase 2} but i don't get the logic still (maybe is just that and i shouldn't be thinking too much about it, don't know).

Would this work if i write my content with that structure in any language?
Could i use any spinner if i write the content with that structure manualy?

Hope you can help me with this because is giving me some problems, and if i buy a license for spinnable-content i don't want to waste money in something that would not work properly.

Thanks.

Matthew Woodward has a great tutorial of how to spin manually: https://www.matthewwoodward.co.uk/
Of course you can spin in every language.
