Excuse my french

Dictionaries between two languages word to word always give a sense of 'half truth' and you're never sure about the accurcy of the translation. Let's say you want to lookup a Spanish word, if you've gotten to the level where you're comfortable using a regular Spanish dictionary then this is probably the best choice. But if you're not there yet, then the definitions in Spanish may require to much effort to understand. My suggestion is to create a Spanish-English dictionary by taking a Spanish dictionary and translating only the definitions to English, this way you get the richness of a dictionary without the risk of not understanding the definition (of course a possible single-word translation can appear at the end of the definition).
