Emily Dickinson Lexicon

CALC'U-LATE, v.i.

To make a computation; as, we calculate better for ourselves than for others. In popular use, this word is often equivalent to intend or purpose, that is, to make arrangements, and form a plan; as, a man calculates to go a journey. This use of the word springs from the practice of computing or estimating the various circumstances which concur to influence the mind in forming its determinations.
