The mixing of language, both global and local enhances multilingualism in the communities of northern Thailand .
Ethnolinguistic interaction in multilingual signs in the region may be understood as a merging of the global and the local,resulting in specific ''globalizad'' linguistic practices .Though globalization has increasingly affected the ways of life of people everywhere including thosein northern Thailand, it also reinvegorates the local soio-cultural identity as reflected in the signs in the predominant local language.Such global social cultural phenomena highlighted in language signs in public spaces indicate the increasing contact of the world's populations in an increasingly borderless era.
