Wordreference or professional
Wordreference is another of those useful resources for translators and language workers. It offers a complete online dictionary in many languages, backed by a forum for the terms that don’t appear in its listings. It can often be lacking in technical terms, where a more robust term search might be more useful, but as a starting point for idiom and day-to-day terms used it can be very useful. As there is little context it can be hard to be certain of which meaning should be used, but overall it’s a very useful tool for a quick check.
