  • Which 'ash'? If it's the wood, use the noun attributively. If it's one of the 'substance left after burning / volcanic eruption' group, it usually wouldn't be homogeneous anyway. What would be 'exactly like ash'? Wouldn't this be ash? – Edwin Ashworth Oct 30 '13 at 22:15
  • it is in a literature context. some boy is compared to ash like he is of the same material. I need the title for the story. it is in Persian. so a word for word translation would be 'homogeneous to ash' at least thats what I have figured out. please help me find the most appropriate translation. – user54495 Oct 30 '13 at 22:19

    We use the word 'homogeneous' to mean 'uniform throughout' - so a homogeneous mixture is a mixture where the components that make up the mixture are uniformly distributed throughout the mixture. It isn't homogeneous to or with anything, it is homogeneous. – Edwin Ashworth Oct 30 '13 at 22:35

    This is not a problem of grammar but of semantics. Homogeneous simply isn't used with that meaning. You should find a different word to get across the meaning you want. – Bradd Szonye Oct 30 '13 at 22:35

    @Hamed You might be thinking of "homologous". In which case: "homologous with" was more common before 1980, and "homologous to" has been more common since 1980. Choose the one you like better. – MetaEd Oct 31 '13 at 4:19

Homomorphic (with alternate spelling homeomorphic) may be the word you are seeking. According to wiktionary it means “Of or pertaining to homomorphism; having a homomorphism”, a homomorphism being “A structure-preserving map between two algebraic structures”, but less generally one can think of a homomorphism as a bijective (that is, both injective and surjective) correspondence between two things. Thus, to say “X is homeomorphic to ash” is to say that X corresponds directly to ash.

    The problem is that if you only took Latin and not Greek, you end up thinking it means man-shaped. :) – tchrist Oct 31 '13 at 0:29
