Pending and impending are easy to confuse. Pending means awaiting an outcome (e.g., a decision, a settlement, a confirmation). Impending means imminent or about to happen.

Something that is pending is awaiting conclusion, confirmation, or fulfillment—for example, the birth of a child, the results of a test, or a just-submitted order from an online store. Something that is impending is about to occur or threatening to happen.

delay or prevent (someone or something) by obstructing them; hinder. “All of this daydreaming is impeding my progress.” be about to happen. “Our moving date is impending.” to obtrude or thrust (oneself, one’s company, etc.) upon others. “I don’t want to impose on your family.”
