Spanish language Q&A Forum

Hi there, I am a little confused as there appears to be inconsistencies in the colouring of letters which are irregular in the verb tables.
In this table only the Z is red, I understand that the letter Z is the main focus of the lesson, however almost all of this verb is irregular, and only highlighting the Z makes me question myself.
In other lessons I have seen emphasis with both red and blue, but there doesn't appear to be a regular pattern, which also casts doubt on my learning.
I know it may be a big job, but would it be possible to devise a standard practice, and then implement? Maybe a job for a Spanish intern :-)

how can Spanish be the second most spoken language in the world? Sure, China is probably # 1 but just the population of the U.S.A. alone at more than 400 million is greater than all the native hispanohablantes. Add in Australia, South Africa, England, Scotland and a few other countries and 2nd and 3rd place must be very close.  Almost every country conducts business in English so there are a lot of English as a second language speakers. Am I missing something?

Suppose I wanted to say something like, "I wouldn't have minded if they got married, I was seeing someone else", or "I didn't care if the wrecked their's appetite with ice cream, I wasn't going to make dinner anyway" is there no combination of tenses that would admit the use o "por mí que"? 

Hola, 

I found this a lot to digest, so re-wrote the lesson to try to understand it better.

Would you be able to do me a big favour and check to see if I’ve understood it correctly?

Muchísimas gracias,
