This document discusses analyzing language to understand how it works and anticipate problems students may have. It analyzes meaning, form, pronunciation, function, and appropriateness. For meaning, problems can arise from complexity, lack of concept in student's language, or multiple meanings. Form issues include word order, rules, parts of speech, regular/irregular forms, spelling, and overgeneralization. Pronunciation issues stem from interference from first language or spelling/pronunciation differences. Function and appropriateness refer to language use depending on purpose, situation, register, and formality. The document provides an example analysis of "I wish I had more time" and suggestions for language analysis.
