Hope is an optimistic attitude of mind based on an expectation of positive outcomes related to events and circumstances in one's life or the world at large. As a verb, its definitions include: "expect with confidence" and "to cherish a desire with anticipation".

Hope combines desire with expectation.

Hope is a small functional programming language developed in the 1970s at Edinburgh University. It predates Miranda and Haskell and is contemporaneous with ML (also developed at Edinburgh). Hope was derived from NPL, a simple functional language developed by Burstall and Darlington in their work on program transformation. NPL was, in turn, derived from Kleene Recursion Equations. NPL and Hope are notable for being the first languages with call-by-pattern evaluation and algebraic data types. SNOBOL is even older, and its 'patterns' may qualify as a hybrid between call-by-pattern and regular expression matching. Hope is an important language in the development of functional programming.
