Etymology
The word 'fief' entered English in the early 17th century from French, where it was spelled 'fieu' or 'fief'. Its ultimate origin is from a Germanic source, likely Frankish fehu, meaning "cattle, property, money." This same root is the ancestor of the modern English word 'fee'. The semantic journey is from the concrete concept of movable livestock, a primary form of wealth in early Germanic societies, to the abstract concept of heritable land held under feudal tenure. Thus, the modern term for a feudal estate retains the ancient logic of property granted by a lord in return for service.
Analysis
The word 'fief' is a simplex loanword from Old French. It does not contain separable, meaningful morphemes in its modern English spelling.
