Both who and whom have roots in Old English:

- Whom comes from hwām, meaning “to whom” or “for whom.”

|---|---|---|
| Formality | Whom often used in formal writing | Whom less common; “who” used more |
| Everyday conversation | Rarely used, considered formal | Rarely used, almost archaic |
| Written English | Maintains traditional grammar | Often relaxed, “who” replaces “whom” |
| Legal/academic writing | Whom preferred for correctness | Whom still accepted but optional |
Example:
- British: To whom should I address this letter?
- American: Who should I address this letter to?
