I was confused about this too when working on documentation for our data platform! FWIW, there is a glossary at https://wikitech.wikimedia.org/wiki/Data_Platform/Systems/Airflow/Developer_guide#Glossary. It seems like that Developer Guide page has become a bit buried compared to the content at https://wikitech.wikimedia.org/wiki/Data_Platform/Systems/Airflow. I just added a link to it on the DAG page Andre referenced, and I modified the Airflow page to try to make the link to https://wikitech.wikimedia.org/wiki/Data_Platform/Systems/Airflow/Developer_guide more obvious.
