If a place or a situation is conducive to something, it makes that thing easier or more likely. A dark, quiet room is conducive to sleep. A noisy café is not conducive to careful reading. The word is rather formal — teachers, reports, and doctors use it; friends in a chat almost never do. It nearly always takes to: conducive to rest, conducive to learning. You use it about conditions and atmosphere, not about a tool in your hand (you would not say this pen is conducive to writing). There is an old verb, conduce, meaning to help bring something about, but it has almost died; conducive is the form that survived. Though actually, people now stretch it a little: not conducive to teamwork can mean the culture feels unfriendly, not only that the room is too hot.
