Step 1: Understanding creolisation.
Creolisation refers to the linguistic process through which a pidgin develops into a fully developed natural languageThis typically occurs across generations
Step 2: Evaluating option (A).
Creolisation indeed involves the elaboration and stabilization of a pidgin languageHence, option (A) is correct
Step 3: Evaluating option (B).
A key feature of creolisation is that children acquire the pidgin as their first language, leading to grammatical expansionThus, option (B) is correct
Step 4: Evaluating option (C).
Creoles develop complex and systematic grammars, although their vocabulary may initially be more limited compared to older languagesThis makes option (C) correct
Step 5: Eliminating option (D).
Option (D) incorrectly describes pidgins rather than creolesCreoles have stable grammars, not limited or highly variable ones
Step 6: Final conclusion.
Therefore, the correct answers are (A), (B), and (C)
