The status of lone nouns of one language in discourse of another is often ambiguous, since they typically provide few indications of their language membership. Making use of the facts of linguistic variability in each of Ukrainian and English, we examine the quantitative conditioning of such forms in bilingual performance data. Results yield a synchronic portrait of the integrated loanword, even when it bears no surface indication of that integration, is neither recurrent nor widespread, and has no history of attestation or other status in the language. Distinguishing the languages involved in the contact situation (Canada) as produced by the first generation (G1) or the second generation (G2), further reveals that G1 speakers incorporate borrowed items - nonce or established - into recipient language discourse by applying to them the fine details of their native language constraints on linguistic variability. In contrast, G2 speakers' treatment of English-origin nouns coincides neither with their own treatment of Ukrainian nouns nor with G1 speakers' treatment of Ukrainian or English-origin nouns.
