Who All Is vs. Who All Are – Which is Correct?
When asking about several people, use “who all are,” not “who all is”: “Who all are attending the meeting?” However, “who all” is informal and especially common in Indian English. In formal or widely edited English, prefer “who is attending?” or “which people are attending?” for greater clarity and naturalness.
Who All Is or Who All Are—Which Is Correct?
“Who all are” is the grammatically appropriate choice when who all refers to multiple people. For example: “Who all are joining us for dinner?” The verb are agrees with the plural meaning of all.
“Who all is” is generally considered incorrect in this context because is is singular. It may appear in informal speech or regional varieties of English, particularly Indian English, but it is not the preferred form in formal or internationally edited English.
There is also an important style point: although who all are is common and understandable, many speakers prefer the more standard alternatives “Who is attending?” or “Which people are attending?”
The Best Trick to Remember the Difference
Use the plural swap test. Replace who all with which people. Because “which people are attending?” sounds correct, choose are: “Who all are attending?” If you are asking about one person, use is: “Who is attending?”
| Word or Phrase | Part of Speech | Meaning | Example |
|---|---|---|---|
| who all is | Question phrase with incorrect agreement | Attempts to ask which people are included | Avoid: “Who all is coming?” |
| who all are | Informal question phrase | Asks which people are included | “Who all are coming?” |
How to Use “Who All Are”
Use who all are when asking which members of a group are involved in an activity, event, decision, or situation. The phrase normally refers to more than one person, so are is used instead of is.
The expression is common in conversation and is particularly widespread in Indian English. It is clear in context, but it may sound informal or regional to speakers of other varieties of English. In formal writing, use “who is,” “which people are,” or “who among them.”
Example 1: Who all are planning to attend the conference?
Example 2: Do you know who all are on the project team?
Example 3: Which people are coming to the ceremony?
Etymology of the Phrase “Who All Are”
Who comes from Old English hwā, an interrogative pronoun used to ask about people. All comes from Old English all, meaning the entire amount or every member of a group. The combination who all developed as an emphatic way to ask about every person in a particular group. Its use is especially established in South Asian English varieties.
Related Concepts
Understanding subject–verb agreement and regional variation helps explain why “who all are” is preferred over “who all is.”
- Subject–verb agreement: A plural subject takes a plural verb. Because who all refers to multiple people, are is the appropriate verb.
- Interrogative pronouns: Words such as who, what, and which introduce questions. Who is used when asking about people.
- Informal and regional English: Some expressions are grammatical and common in particular English varieties but less usual in international formal writing.
- Formal alternatives: “Who is attending?”, “Which people are attending?”, and “Who among them is attending?” can sound more natural in formal contexts.
Examples from Media and Literature
The following examples show how the idea can appear in dialogue, reporting, and narrative contexts. The formal alternatives are often preferable in edited publications.
- Conversational dialogue: “Who all are coming to the school reunion?”

- News-style wording: “Officials announced which people would attend the summit.”
- Literary-style narration: “She wanted to know who among the villagers had seen the traveler.”
