Sometimes, in German, I want to describe a plural of an objects for instance:
Die Delphine können mit den Menschen in gewisser Weise kommunizieren.
Dolphins are able to maintain certain communication with humans
Now, for the most part, the sentence makes sense to me, but I can't understand why we need the "Die" i.e.
Delphine können mit den Menschen in gewisser Weise kommunizieren.
Is the definite article really that necessary? I thought the top instance was more formal than the second one (i.e. for colloquial speech) but I wasn't sure.
Delphine können mit Menschen in gewisser Weise kommunizieren.
