Sensu is a Latin term meaning "in the sense of". It is used in fields including biology, geology and law in the phrases sensu stricto or stricto sensu ("in the stricter sense") (abbr.: s.s.), [1] and sensu lato or lato sensu ("in the wider sense") (abbr.: s.l.).[2] . In rare cases the superlatives sensu strictissimo ("in the strictest sense") and sensu latissimo ("in the widest sense") may be used. Another common usage is in conjunction with an author citation, indicating that the intended meaning is the one defined by that author.
