Let me provide a homey example. I put together the ingredients to bake a cake. I can tell you what ingredients are in the cake, but if you put all the ingredients on the counter, it's not a cake. The cake is an emergent property of a specific combination of ingredients in a specific proportions exposed to specific environmental conditions.
Now, could the cake have some "independent effect" on something else? Sure. But that effect is the effect of the emergent property, not the effect of any of the individual ingredients that went into the cake.
And just so with any human traits or characteristics, including language.
