Spanish language Q&A Forum

I had a really big cup of coffee this morning!

Your answer to Marcos does not explain why a feminine version exists since, as you say, 'When we form a noun using the augmentative suffix -ón, the new word is always masculine, regardless of the gender of the originating noun. This is because nouns ending in -ón are generally masculine’.

Greetings everyone
I would like to ask why the correct answer is the option:
La persona con quien fui a la fiesta era mi padre

while the answer

La persona con la que fui a la fiesta era mi padre
is marked as nearly correct when both options are acceptable, according to the lesson above.

Why does my lesson include 'vosotros'/'sois'and other lessons from European Spanish.  I am trying to learn Latin Spanish and have set my account to Latin Spanish.  This is very confusing if you actually try to teach me a different language to the one that I chose. 

I thought gustar was modified by the thing being liked (vs the person/people doing the liking), but when I chose gustan for liking the horse races I was marked wrong. 

I don’t understand why the 2nd sentence (starting “Fue”) uses the indefinido but the 3rd sentence (starting “La lengua” uses the imperfecto. I can’t really see any difference between them and I thought they should both be the imperfecto tense since they refer to something that happened over a long period. Likewise tense choices in the later sentences. Thanks for your help, Tony
