👉 The term "preestablishing" is a colloquial idiom that refers to something being established or formalized before it has been fully developed or understood. It implies that something has already been established, established by another party, or has been formally recognized. For example, if someone says they have "preestablished their opinions" or "have pre-established their views," it means that they have already had a discussion about the topic and come to a consensus on certain points.
