Was Used vs. Was Use – Which is Correct?
Was used is correct in standard English when you need the passive form of the verb use: “The tool was used carefully.” “Was use” is incorrect because was requires a past participle in this construction. Use “used” after was, although “use” can follow did, will, or to in other structures.
Was Used or Was Use – Which is Correct?
Was used is the correct phrase when expressing the passive voice in the past tense. It means that someone or something used an object, method, or opportunity, but the sentence focuses on what received the action.
Was use is incorrect in standard English. The error usually results from confusing the base form use with the past participle used. After the helping verb was in a passive construction, the past participle is required.
The Best Trick to Remember the Difference
Use the “was + -ed” test. When was introduces a passive action, choose the past participle: was used, was cleaned, was repaired, or was explained. If you can replace was with did, the base form may be correct: Did you use it? Never say was use to express the passive voice.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| was used | Passive verb phrase | Was utilized, employed, or put into action | The old bridge was used for many years. |
| was use | Incorrect phrase | A grammatical error caused by using the base form after was | Incorrect: The old bridge was use for many years. |
How to Use Was Used
Was used is the past-tense passive form of use. It is appropriate when the person who used something is unknown, unimportant, or intentionally omitted. The structure is subject + was + used, often followed by by and the person or thing responsible for the action.
This phrase is common in formal, academic, technical, and everyday writing. It can describe a tool, object, method, phrase, location, resource, or procedure that someone used in the past.
Example 1: The laboratory equipment was used to measure the temperature.
Example 2: This expression was used frequently in nineteenth-century novels.
Example 3: The conference room was used by several departments last week.
Etymology of the Word Used
Used comes from the verb use, which entered English through Old French from Latin uti, meaning “to employ,” “to make use of,” or “to enjoy.” The ending -ed marks the regular past tense and past participle. In was used, was supplies the past tense while used forms the passive participle.
Related Concepts
Understanding passive voice and verb forms makes the difference between was used and was use easy to recognize.
- Passive voice: Passive voice emphasizes the person or thing receiving an action. In “The key was used,” the key receives the action, while the user may not be mentioned.
- Past participle: A past participle is used with helping verbs in perfect and passive constructions. For the regular verb use, the past participle is used.
- Base form: The base form is the simplest form of a verb, such as use. It appears after words such as to, will, can, and did.
- Subject-verb agreement: The singular subject in a past passive sentence takes was, while a plural subject generally takes were: “The method was used” but “The methods were used.”
