We are using Google translate when we are translating words/sentences into another language.
But what if I want to lookup what a word means in my own language or in English.
Is there a Google dictionary for such things?
If you go to Google Dictionary, there is a dropdown that lets you pick a language pair (source & target languages can be different) or the dictionary for a specific language (available only for a few languages) & then looks up the meaning of a submitted word.
There is an online Wiktionary in your language. When I choose the "Deutsch" Wiktionary, and type in a word -- it doesn't matter if that is an English word, a Spanish word, a German word, etc. -- it gives me the definition(s) of the word I typed in German.
Wiktionary also allows you add the (by now, relatively few) words that haven't yet been added to the dictionary.
