idem sonans adj
[Latin, sounding the same]
: relating to or being two names having the same or similar pronunciation or sound [the two names are not idem sonans "Johnson v. Estelle, 704 F.2d 232 (1983)"] [the idem sonans test] compare misnomer NOTE: An idem sonans name allows a pleading or other document (as a warrant) to be considered valid despite the minor misspelling of a name or other misidentification of a party (as in identifying a corporation as a partnership). The fact that two trademarks are idem sonans may be used to establish the likelihood of confusion on the part of consumers in a trademark infringement case.
