Now, don’t get me wrong. A decent dictionary and thesaurus are a must (personally, I use the Oxford editions) but sometimes when writing a paper – or even your thesis/dissertation – you can get stuck.
It happens to me frequently, as I think in two languages at once and every now and then, my brain freezes and I can’t think of the word in either language. So I paraphrase, or describe what I want to say.
This website lets you do just that but then also gives you the word instead of leaving you with an awkwardly paraphrased sentence.
