The following links take you to monolingual English dictionaries you will find useful for my classes.
Longman Dictionary of Contemporary English
This is the standard dictionary for my courses. It is an excellent dictionary for learners of English because it provides you not only with definitions and example sentences, but also with information as to collocations, synonyms and word families.
You will find a Learner's Dictionary and a bilingual English-German, German-English dictionary here.
Collins English Thesaurus
If you are looking for synonyms and alternative phrases, a thesaurus is where you look them up. This is one of the best-known ones.
I have been asked repeatedly which resources you can use to improve your grammar on your own. There are numerous sites on the web, but I admit to not being able to recommend any language learning sites specifically. However, the dictionaries I mentioned in the other post also provide grammar tasks (to an extend). Also, there is a series in Cambridge University Press that I always use in class (yes, old-fashioned printed books). Please find the references below:
Longman Dictionary of Contemporary English - English language exercises
Cambridge Dictionary - Grammar
You will find a great variety of exercises - from simple grammar tasks to complete online courses - on this site run by the British Council (my link takes you to the grammar page):
British Council - Learn English
And a site started by two Germans - an English tutor and a programmer - with information and exercises on a great number of topics and skills:
