• Squander implies starting with many resources, such as great wealth, and then wasting them (using them up to little purpose or little effect), often ending with little. Particularly used in phrases such as squander an opportunity or squander an inheritance. It may be used even if one starts with little, though usually in some construction such as squander what little he had.
