Two cultures — “bicultural”, one culture —?

Question

I am looking for a word that means that somebody only has one culture. For example, somebody immigrating from Country 1 to Country 2 would be bicultural. What is someone who has only one culture. I thought unicultural but I don't think that is correct.

Answer 1

Monocultural is what you want. One of the meanings of the noun monoculture is, in the OED’s definition, ‘A common culture or way of life; (now) especially a culture or way of life which is ascendant over a large (or global) area; a dominant cultural hegemony’ and it has been in use since 1968. The corresponding adjective monocultural is first recorded by the OED four years earlier.

The OED has no entry for unicultural.

Answer 2

I go with Monoculture, as pointed out by LaceySnr's comment. Webster defines monoculture as

a culture dominated by a single element : a prevailing culture marked by homogeneity

There is also a reference to mono-culturalism in this article of Wikipedia.

Answer 3

The etymology of culture (meaning 'The distinctive ideas, customs, social behaviour, products, or way of life of a particular nation, society, people, or period. Hence: a society or group characterized by such customs, etc.') is rather complex. It essentially boils down to this: Latin via French and influenced by German.

We can use the uni- comb. form (which comes from Latin, we would not use mono- which is generally combined with words with Greek origins), which OED defines as:

Forming adjectives with the general sense ‘having, provided with, composed or consisting of, or characterized by one (thing specified or connoted by the second element)’.

Thus, I would say a person without only one culture would be unicultural, though one would be hard pressed to find this in any dictionary.
