Sense: noun/1
All three words describe catching fish, but they differ in scope and method. 'Fishing' is the broad, everyday term — it covers every technique from using a simple hand line to commercial trawling. 'Angling' narrows this to a specific method: using a rod, line, and hook, usually as a sport or hobby rather than for a living. 'Fly fishing' is a sub-type of angling that uses an artificial 'fly' as bait and a specialised casting technique. In casual conversation, a person holding a rod by the river is 'fishing'; only in more careful or technical writing would a speaker say they are 'angling'. For example: 'We went fishing at the lake' (natural) versus 'We went angling for pike' (more deliberate, specifying the rod-and-line method).
Etymology
The word 'angling' comes from the Old English noun 'angel', meaning 'fish hook'. This 'angel' is related to the word 'angle' (the geometric term) because a fish hook is bent at an angle. The modern sense of fishing with a rod and hook took its current form in the 1500s.
