The word "采取" is formed through the semantic fusion of its two constituent characters: "采", which originally depicts a hand plucking fruit from a tree, conveying the core idea of selecting or gathering, and "取", which historically represents a hand taking an ear (as in war trophies), emphasizing the act of seizing or obtaining. When combined, these characters merge their overlapping notions of active acquisition, where "采" contributes the nuance of careful choice or collection from among options, and "取" adds the decisive action of laying hold of that selection. This synergy creates a composite meaning that encompasses the entire process of deliberately choosing and then implementing something, such as a measure or strategy, hence yielding the modern sense of "to adopt" or "to take".
