Used by Hispanic-Americans(ME) to speak to other Hispanic-Americans whom can understand both Spanish and English. When a person can't remember how to say a word in spanish, they say in English, and vice-versa
Often used in the Latino community, or used by white kids trying too look cool and exotic.
Sometimes this will be the end result of a half-assed public school spanish education.
One small detail I noticed with Spanglish is that speakers use cognates a lot.
Look I can speak Spanglish,
Hola, mi amigo, do you want to go to the restaurante to get tacos and burritos?
combination of english and spanish words, spoken with the non-english accent and often contains words that are of neither language, or words with elements of both languages. may be spoken by someone who doesnt speak spanish and/or english well, or someone who speaks both very well. often used intelligently by switching languages for emphasis. also spoken by "latinos" in the united states who share parts of U.S. culture and culture from a latin american country, and prefer speaking both languages instead of one or the other (also can interchange languages at will).
parquear (par-ke-ar:, in english "to park" a vehicle, in spanish "estacionar") is an example of a spanglish word.
