Definition

Need and needed are two words that are often used interchangeably, but they actually have distinct meanings. Need is a verb that expresses a requirement or necessity for something. For example, "I need to eat" indicates a necessity for food. On the other hand, needed is the past tense and past participle of need, indicating that something was required in the past. For example, "I needed to eat yesterday" shows a requirement for food in the past.

Usage

Need is used to express a current or ongoing requirement for something. It is often followed by an infinitive verb, such as "to eat" in the example above. Needed, on the other hand, is used to indicate that a requirement existed in the past. It is often followed by a past participle, such as "to eat" in the example "I needed to eat yesterday."

Formality

Need is generally considered more informal than needed. Need is commonly used in everyday speech and informal writing, while needed is often used in more formal contexts. For example, in a business email, you might say "I needed your report by yesterday" rather than "I need your report by yesterday."

Emphasis

Using needed can sometimes add emphasis to a statement. For example, saying "I needed to leave immediately" can convey a sense of urgency or importance that might not be as strong with "I need to leave immediately." The past tense of needed can give the statement a sense of finality or certainty.

Negation

When negating a sentence, need and needed are used differently. Need is negated by adding "not" before the verb, as in "I do not need to go to the store." Needed is negated by adding "did not" before the verb, as in "I did not need to go to the store yesterday."

Examples

• Need: "I need to study for my exam."
• Needed: "I needed to study for my exam last night."
• Need: "She needs to finish her project by Friday."
• Needed: "She needed to finish her project by last Friday."
