Espouse is derived from the Old French word 'espouser' (meaning to marry or to betroth), which in turn comes from the Latin 'sponsare' (meaning to betroth or to promise). The word 'espouse' means to adopt or support a cause or belief, as well as to marry.
Think of 'espouse' as adopting or 'promising' ('sponsare') to support something, just like one would promise to love and support a spouse.
