daffodil or jonquil?

I just read a few articles about the difference between daffodils and jonquils. 
I grew up calling everything like this a jonquil. We never used the term daffodil. I think this is because I had an aunt named Daph, and we didn't want to get confused. Good thing I didn't have an uncle named Jon!
Turns out a jonquil is a specific type of daffodil, usually all yellow, with a cluster of blooms coming from one stem.
So this seems to be a daffodil! And a sure sign Spring has sprung here.
