Meaning

noun an impression that something might be the case

noun doubt about someone's honesty

noun the state of being suspected

originFrom Middle English suspecioun, borrowed from Latin suspīciō, suspīciōnem, from suspicere, from sub- (“up to”) with specere (“to look at”). Perhaps partly through the influence of Old French sospeçon (or rather the Anglo-Norman form suspecioun). Equivalent to suspect + -ion.
