"Whoever" acts as the subject of the clause it introduces; "whomever" acts as the object of the clause it introduces.
"Whoever" functions as the subject within its clause. If you can replace it with "he" or "she" inside that clause, you need "whoever".
Whoever is responsible for the error should report to the manager immediately.
The award will go to whoever demonstrates the most consistent improvement over the semester.
Whoever finishes the task first can leave early, the rest should stay until 6 p.m.
"Whomever" functions as the object within its clause. If you can replace it with "him" or "her", you need "whomever". In informal speech, "whoever" is used for both.
She said she would give the position to whomever the panel recommended, the final decision was theirs.
You may invite whomever you like to the company dinner, space is not limited.
The contract will be awarded to whomever submits the most competitive bid by the deadline.
Common mistake
The error: "Give the award to whoever the committee selects" = wrong, the clause says "the committee selects him/her" (object), so it must be "whomever the committee selects." In everyday speech "whoever" has almost completely replaced "whomever"; in formal writing and exams, the distinction still matters.
Trick to remember it
Same trick as who/whom: substitute inside the clause with "he/she" or "him/her": "he/she" (subject) = "whoever"; "him/her" (object) = "whomever." "Whomever you invite" → "you invite him" (object) = "whomever."
Quick rule
Did you know?
WHOMEVER is today one of the rarest words in spoken English, many native speakers never use it and always fall back on WHOEVER. Linguist Steven Pinker, in "The Language Instinct," argues that the WHOM/WHOMEVER distinction is so complex that even expert grammarians make errors when choosing. Some modern style guides directly recommend avoiding WHOMEVER in speech and using it only in legal documents where formal precision is essential. In 21st-century informal English, WHOEVER for both functions is practically universal.
