For example, if you were to say that something is particular to only one race, you’d say the trait is “race-specific”. So my question is, what is the opposite of this? I would say it’s “race-inspecific”, since that sounds correct to me and “race-unspecific” doesn’t seem to make sense. Neither does “race-nonspecific”.
I think the word I was looking for is “dependent” and “independent”.
I think usually, using your example, you would say ‘non-specific to race’, ‘independent of race’, or maybe ‘race-independent’ (although the last one doesn’t sound quite right).
Perhaps use ‘non-race-specific’?
