NOUN + 以外 as “except for NOUN”
The word 以外 (igai), consisting for the characters 以 to mean “in view of, compared with, etc.” and 外 to mean “outside, exterior, etc.” can be used with a noun to literally mean “in view of everything outside that noun.” More naturally, this will translate to “except NOUN, with the exception of NOUN, other than NOUN, besides NOUN, apart from NOUN, etc.” When this grammar pattern is employed, it is often but not always followed by the particle に or は.
