The second meaning is abstract: “apoyo la idea de trabajar 5 días a la semana” that means I agree with that idea Respaldo is an element of a chair or seat, the element in contact with your back: “El candidato cuenta con el respaldo del president” – the candidate has the approval and support of the president.

Doubt vs. Question Hi, Derek. You have questioned (seeking more information) me about my previous comment. In case you doubt (don't believe) what I said is true, I will provide you with some corroborating links: :) a. https://englishtips.quora.com/Doubt-vs-Question b. http://english.stackexchange.com/questions/13913/questions-vs-concerns-vs-doubts (excerpt: In current American English, 'doubt' could be considered to be a synonym of 'question', but the difference is that 'doubt' implies LACK of BELIEF rather than lack of KNOWLEDGE.) ========== Let me also provide you with some common examples of the use of "doubt" and "question" in English. 1. (at the end of a meeting or class) Are there any questions? (seeking information to clarify points of misunderstanding or confusion) 2. (during a meeting) Are there any doubts about this plan? Yes, I don't believe it will work. It will require more time and money than we have available. 3. A: Do you think it will rain tomorrow? B: I doubt it. (I don't believe it will rain.) The weatherman said there would be no rain all week. 4. A: John said he would do it by next week. Do you think he can do it? B: I doubt it. (I don't believe he will do it.) He's always late on all his tasks. 5. I doubt you can do it. (don't believe you can) I think you've bitten off more than you can chew. 6. I doubt his story. (I don't believe what he is saying is true.) 7. I have one question. Can you explain what you mean by "compound adjective"? (seeking more information) 8. Wife: I can do this. Husband: I have no doubt. (I believe you 100%) 9. If there is any doubt (non-belief) in anyone's mind that this mission is worth risking your life for, then you should not volunteer. Failure is not an option. If you have any further questions (seek more information), let me know. I hope you no longer doubt (don't believe) me when I say that "question" and "doubt" are very different.

We explain "in detail". I have a doubt => you don't believe that something is true. There are no doubts in grammar. The rules are explicit. I have a question => I don't know something, so I need more information. You have a question, not a doubt.
