The Bridge is the pre-planned instructional moment when teachers bring Spanish (or other non-English language) and English together to encourage students to explore the similarities and differences in the phonology (sound system), morphology (word formation), syntax and grammar (word order of sentences and other language rules), and pragmatics (language use) between the two languages, that is, to undertake contrastive analysis and to transfer what they have learned from one language to the other.  The Bridge occurs in transitional bilingual, dual language, one-way immersion, two-way immersion and ESL instruction.
