Whoever vs. Whomever

“Whoever” is the subject form inside its clause; “whomever” is the formal object form. The key is the pronoun’s role inside the embedded clause, not simply whether a preposition appears before the entire clause. Informal English often uses “whoever” where formal writing may use “whomever.”

Quick answer

Choose by the pronoun’s job inside its own clause: subject → “whoever”; formal object → “whomever.” “Give it to whoever finishes first” is correct because whoever is the subject of finishes, even though the whole clause follows “to.”

Informal English often uses whoever in object contexts.

Quick tests

Inner-clause pronoun test

Inside the clause, would “he/she/they” fit rather than “him/her/them”?

If yes: Use “whoever.”

If no: Formal writing may use “whomever” if the object forms fit.

Caveat: Informal English often uses “whoever” in object contexts where formal style may prefer “whomever.”

Examples

Further guidance

Inner Clause Rule

The case decision belongs to the inner clause: ask whether the pronoun performs the action or receives it there.

Preposition Trap

A preceding preposition does not automatically force whomever when its object is an entire clause whose internal subject is whoever.

Whomever Register

Cambridge presents whomever as a formal object form and notes that informal English commonly uses whoever instead.

Who vs. Whom

“Who” is used for subjects and is also common for objects in ordinary modern English; “whom” is the traditional object form and remains most common in formal writing, especially after a preposition.
