Both firth and fjord are now generally defined as an arm of the sea. The difference is crucial - a firth (or fjord) is made up of undiluted sea water, but an estuary has a gradation of salt water dilution from fully salt water at its mouth to fresh water at its head, and experiences tidal fluctuations
