the word suspicion originates from the latin verb 'suspicere', meaning "to look up at, mistrust, suspect". this verb is a compound of 'sub-', signifying "from below" or "secretly", and 'specere', "to look". thus, the literal sense is "to look at secretly from below", conveying the idea of a wary, distrustful gaze. over time, this action evolved into the noun 'suspicio', denoting the state or feeling of mistrust. entering english via old french 'sospeçon', the word retained its core meaning of a belief in possible wrongdoing or danger, capturing the act of regarding someone or something with concealed doubt.
