Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
1. suspector, āri, v. suspecto fin.
2. suspector, ōris, m. [1. suspicio], one who looks up to or respects a thing, a respecter: morum vestrorum suspector admiratorque, Sid. Ep. 3, 5.
