Etymology

The word "suspicious" originates from Latin "suspiciosus," derived from "suspicere" (to look up at, mistrust). The morpheme "sus-" (a variant of "sub-") implies something hidden or beneath, while "spic" comes from "specere" (to look). Combined with the suffix "-ious," it forms an adjective meaning "inclined to look at something with distrust." Over time, the meaning evolved to emphasize doubt or wariness about hidden motives or dangers.
