"Insufficient" or "inadequate" refers to a situation where something is not enough to meet a particular need or standard. This can apply to various contexts, such as resources, information, or support. For example, if a student receives insufficient feedback on an assignment, they may struggle to improve their work. Inadequate resources can hinder progress in many areas, including education, healthcare, and business. For instance, a company with inadequate funding may struggle to launch a new product, while a hospital with insufficient staff may not provide the best care for patients.
