the word 'valued' originates from the past participle form of the verb 'value', which entered english in the 15th century from old french 'valoir', meaning "to be worth". this old french term derives from latin 'valēre', signifying "to be strong, be well, be of worth". the latin verb has a deeper ancestry in the proto-indo-european root wal-, meaning "to be strong". the semantic journey thus progressed from a concept of physical strength and health in the ancient root, to one of worth and efficacy in latin, and finally to the modern abstract senses of estimated monetary worth and high esteem. the '-ed' suffix here is not a separate morpheme but an integral part of the participial adjective formation, indicating a state resulting from the action of the verb.

the word is a simplex form derived from the past participle of the verb 'value'. it is not productively segmented into smaller, independent morphemes in modern english.
