Mount Everest goes by two other names. What are they?

Mount Everest's other two names are Sagarmatha and Chomolungma
(alternate spellings include Qomolangma, Chomolangma, and Jolmo
Lungma).

"Mount Everest is named for Sir George Everest, who surveyed India for
the British from 1806 to 1843. In 1830 he was named surveyor-general.
Before 1865, Mount Everest was known as 'Peak XV.'

The Nepalese word for Mount Everest is Sagarmatha, meaning 'goddess of
the sky.' In Tibet, Mount Everest is called Qomolangma (Chomolangma),
meaning 'goddess-mother."

Just a small comment / correction:
Sagarmatha actually means "having its forehead in the sky", its
Sanskrit roots are, Sagar: sky, matha: forehead.
This name was given by the eminent Nepalese historian Baburam Acharya
about 30 years ago.
