The term "as needed" does not have a specific etymology, as it is a combination of two common English words. "As" is derived from the Old English word "ealswā", meaning "equally so" or "just as". "Needed" comes from the Old English word "nēodian", which means "to require" or "to be necessary". When these two words are combined, "as needed" simply signifies that something should be done or used when it is necessary or required.
