Relating to or involving calculation; having the capacity or tendency to calculate or think strategically.
From calculate plus the suffix -ive, which forms adjectives meaning 'tending toward' or 'relating to.' This suffix creates adjectives from verbs.
Calculative, calculational, and calculatory all exist as similar adjectives, but linguists notice that calculative often describes human nature ('a calculative person'), while calculational describes processes ('calculational errors')—subtle distinctions that help English speakers be more precise.
