In spoken language analysis an utterance is a smallest unit of speech. It is generally but not always bounded by silence. It can be represented and delineated in written language in many ways. Note that in such areas of research utterances do not exist in written language, only their representations do. In other fields it is medium-neutral and refers to any use of language in context (in contrast with the abstract form sentence).

Expression Language (EL) is a scripting language which allows access to Java components (JavaBeans) through JSP. Since JSP 2.0, it has been used inside JSP tags to separate Java code from JSP, and to allow easier access to Java components (than in Java code).
