The argument structure constructions(ASC)sanction innovative instances through two approaches,namely replication and alignment.If there is no conflict in form and meaning between new verbs and ASC,the features of the ASC can be replicated into the semantic domain of the new verbs to generate innovative instances,a process termed"Sanc-tion by Replication".If form and meaning mismatch is found between new verbs and ASC,then the solution is to adjust the verbs'argument structure via construction coercion,allo-wing new verbs and ASC match and making new verbs the core head of innovative instances.This approach is called"Sanction by Alignment".The two approaches exhibit significant differences in terms of both the mechanisms behind and the consequences caused.The dia-chronic extension of the ASC relies mainly on Sanction by Replication supplemented by Sanc-tion by Alignment.
