Does the term 'at most' mean there is at least one?

No because

"at most one"


one or less.

The free dictionary points out that at most can be replaced by "not more than".

In which case

  • at most one can be equated to not more than one,

whereas instead

  • at least one means not less than one.

Alain, thank you very much. Do you have a resource for this, I tried searching everywhere online, didn't have any success. – KerxPhilo May 5 '11 at 6:06
@KexPhilo, I've edited the answer to start from a dictionary definition, if this is what you are after. – Alain Pannetier Φ May 5 '11 at 6:20

It means "no more than one." Many times it is used to imply "no more than one, if even that."
