Etymology
the word 'ebb' originates from the old english term 'ebba', which referred to the receding of the tide. this old english word is cognate with other germanic terms like old frisian 'ebba', middle dutch 'ebbe', and old norse 'efja', all sharing the core meaning of low tide or a backflow. the common germanic root abjōn- is likely connected to the proto-indo-european root apo-, meaning 'off, away', which logically underpins the concept of water moving away from the shore. over time, this concrete, physical meaning was metaphorically extended to describe any process of weakening, fading, or decline, moving from the literal tidal movement to abstract states of diminishment.
Analysis
this word is a simplex form. it is a loanword from old english, which itself derived from a common germanic root.
