This chapter reviews a series of replications of the studies reported in previous chapters on eight typologically distinct language pairs, making use of a wide array of phonological, morphological, and syntactic diagnostics (e.g., vowel harmony, word order, case-marking, adjectival expression, nominal determination patterns, verb incorporation strategies). Wherever a conflict site between donor and recipient languages could be determined, lone items were systematically shown to behave like the latter, often to the point of assuming the fine details of its variable quantitative conditioning. Results confirm that the integration process and its outcome—grammatical identity of donor-language items with recipient-language counterparts—are universal.
