the word 'traitorous' originates from the latin verb 'tradere', meaning 'to hand over' or 'deliver', which is itself a compound of 'trans-' (across) and 'dare' (to give). this literal sense of handing something over evolved metaphorically into the act of betrayal, as in handing someone over to an enemy. the agent noun 'traditor' (traitor) was formed, and the english adjective 'traitorous' developed by adding the adjectival suffix '-ous' to the anglicized stem 'traitor', creating a word that characterizes someone or something as full of the qualities of a betrayer.

Structure: trait (deliver, hand over) + or (agent suffix) + ous (adjective suffix) "trait" from latin 'traditor', meaning 'one who hands over', from the verb 'tradere' (to hand over, deliver, betray). "or" is a latin-derived agent noun suffix. "ous" is a latin-derived suffix forming adjectives meaning 'full of' or 'characterized by'.
