Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
angŭlo, āre, v. a. [angulus], to make angular or cornered, Ambros. Ep. 42.
Hence, * angŭlātus, a, um, P. a., made angular; with angles, angular: corpuscula, Cic. N. D. 1, 24.
