guarded

the word 'guarded' originates from the old french verb 'garder', meaning to watch or protect, which itself has germanic roots, likely related to the old high german 'wartēn', meaning to watch. the suffix '-ed' is a common english adjectival suffix derived from old english, used to form past participles of verbs and subsequently adjectives. the literal meaning, 'being protected', evolved into the modern abstract sense of being cautious or non-committal, as if one's thoughts or feelings are being protected or kept under watch. thus, a 'guarded' response is one that is carefully protected from revealing too much.

Structure: guard (to protect) + ed (adjective suffix) guard (from old french 'garder', meaning 'to watch, keep, protect', of germanic origin) + ed (old english suffix forming adjectives from nouns or verbs, indicating possession of a quality or being in a state).
