Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
dis-convĕnĭo, īre, v. n., to disagree; to be inharmonious, inconsistent (very rare): aestuat et vitae disconvenit ordine toto, Hor. Ep. 1, 1, 99.
Impers.: eo disconvenit inter Meque et te, Hor. Ep. 1, 14, 19: disconveniens deo, Lact. de Ira D. 3, 1.
