I will look further at the notion of simplification as a psycholinguistic strategy applied to a target language […].
- Romaine (1988), Pag. 32

[…] simplification will have psycholinguistic consequences, since one can expect that greater generality of rules and fewer exceptions in grammar make a language easier to learn.
- Romaine (1988), Pag. 32

Simplification of form does not necessarily entail impoverishment of meaning, ie loss and lack of certain means of expression.
- Romaine (1988), Pag. 32

[…] simplification begins with the verb, extends to the noun, then the copula, and then finally the pronoun system.
- Romaine (1988), Pag. 81

I will use the term 'simplification' here in the sense in which Mühlhäusler [Mühlhäusler, P. (1974). Pidginization and Simplification of Language. Pacific Linguistics B-26. Canberra: Australian National University.] defines it as an increase in regularity.
