What does 1dc in next dc

This. Is a crochet  term

[magiccrochetfan]

Simply put, it means exactly what it says.  the next dc that appears in the row or round you are working into is the "next dc".  make a dc into that stitch.  

Do you know what dc stands for?  It means the double crochet stitch.  the pattern should include a key to all abbreviations used; often it is helpful to write out the pattern for yourself using complete words, until you memorize the abbreviations....or anytime when working a complex pattern really.  

Are you working a pattern for the first time?  it's a good idea to do a little studying before you jump into a pattern.  here is a quick introduction to reading and using patterns https://www.craftyarncouncil.com/standards/how-to-read-crochet-pattern   

I recommend getting a good reference book, like Crochet Answer Book or Crocheting for Dummies.   That way you can look up what you need to know and not have to post a question and wait for a reply.  Also you can read ahead to help you understand, before a question arises.  

Also you might like to search out patterns that include a phototutorial or at least several illustrations of the steps.
