Emily Dickinson Lexicon

CON'VERSE, n.

1. Conversation; familiar discourse or talk; free interchange of thoughts or opinions. Formed by thy converse happily to steer / From grave to gay, from lively to severe. – Pope.
2. Acquaintance by frequent or customary intercourse; cohabitation; familiarity. In this sense, the word may include discourse, or not; as, to hold converse with persons of different sects; or to hold converse with terrestrial things.
3. In mathematics, an opposite proposition; thus, after drawing a conclusion from something supposed, we invert the order, making the conclusion the supposition or premises, and draw from it what was first supposed. Thus if two sides of a triangle are equal, the angles opposite the sides are equal; and the converse is true; if these angles are equal, the two sides are equal. – Chambers. Bailey.
