Translation of wärmen

I think we will start Spanish-English and then German-Spanish. Were my explanations clear that when the correct word appeared in the alternative suggestions one needs just to press skip? I think it is normal.
In plural there is no difference between the formal and the colloquial address form. Do you mean that you are using 3rd person singular form for the plural imperative? If so, I will change all entries so far.
Thank you for your kind message. I have not done anything for my Spanish because I have too much work at my job. I might write you a letter, but I'm so busy at work that I can't afford other hobbies.
