Synonym discussion
Sense: adverb/1
'Otherwhere' means 'in another place', but it sounds rare and literary in modern English. 'Elsewhere' is the normal modern choice in both speech and writing: 'The files are stored elsewhere.' 'Somewhere else' is even more conversational and often appears when a speaker changes plans: 'Let's sit somewhere else.' 'Anywhere else' is different because it is used in negatives, questions, or broad choices: 'Would you rather live anywhere else?' If you want plain modern English, choose 'elsewhere' or 'somewhere else'. Use 'otherwhere' only when you want an old-fashioned or strongly literary tone.
Etymology
Built from 'other' and 'where', this word developed in older English as a way to mean 'in another place'. It survives mostly in literary or old-fashioned use, while modern everyday English usually prefers 'elsewhere'.
