The metalinguistic focus for the Bridge is determined by the needs of the students and by the words or phrases that will be bridged.  For example, if there are many cognates among the words to be bridged and students have not yet learned about cognates, then cognates would be an appropriate area for metalinguistic analysis.  If, on the other hand, there are few cognates among the words bridged, but there are words with j and h, and students are interchanging the j and h in their writing, then the phonological difference between j and h in Spanish and English would be an appropriate metalinguistic focus.
