    Meanings

    Adverb

    1. in a continuously active or expressed biological state

    2. as an inherent or defining part of something

    Beyond the definition

    Imagine building with LEGO bricks. Some bricks are just there, acting as the base structure—they're essential to how the whole thing is built, not added on as an afterthought. That is what "constitutively" means! It describes something that exists as a fundamental part of something else, inherent in its very nature. A robin is constitutively different from a penguin; those differences are baked into their biology, not just a temporary state.

    Think of it like this: you can choose to be happy today, but your brain might be constitutively wired for certain emotional patterns. It's about what something is at its core. In science, you might hear that a particular protein is "constitutively expressed" in cells—this means the cell produces that protein all the time as part of its basic function, rather than only making it when triggered by an outside signal.
