[TYPO3] removing one language from multi language site

[Zaw Min]

Hello list,

  How can one language be removed from a site setup with one tree multi
language concept?The site is setup in French and English with French as the
first language. Now we want to use only English which is currently set up as
alternate language. How can we disable the French pages? I would appreciate
some suggestion or link to a guide to read.

Thanks,
ZM
