Chapter 9 is devoted to aspects of general extender use by second language (L2) learners, with discussion of research and examples from first language (L1) speakers of Dutch, French, German, Persian and Swedish, plus data from English L1 speakers learning other languages. The phenomenon of low-frequency use of discourse/pragmatic features among L2 learners is noted. The more limited repertoire of L2 learners results in the complete absence of some forms and a reliance on, and hence overuse of, only a few expressions. Another aspect of L2 learner usage is the creation of novel expressions, some of which can be analyzed as interlanguage forms. Novel forms, and new uses of old forms, are also exemplified in the use of English as a lingua franca. Proposals for the inclusion of general extenders in L2 teaching are based on the explicit presentation and analysis of examples, with a contrastive approach discussed and exemplified. The chapter concludes with four exercises designed to raise awareness of how different English general extenders are typically used.
