Spanglish is the mixed way of speaking that happens when Spanish and English live in the same mouth. It is most common in the United States, especially among people with family roots in Mexico, Puerto Rico, Cuba and other Spanish-speaking places — but you also hear it in Puerto Rico itself, along the Mexican border, and in Gibraltar and Panama. What does the mixing look like? Three things, really. (1) A speaker starts a sentence in one language and finishes it in the other: "I told her que no." (2) English words get Spanish shapes: parquear (to park), la troca (the truck), textear (to text). (3) Spanish words get pulled into an English sentence because they simply fit better — no ganas, mija, ya. One thing to hold on to: this is not broken language, and it is not a sign that someone speaks either language badly. Switching between two languages mid-sentence takes real skill; you must know both well enough to know where the join can go. Linguists call this code-switching and study it seriously. But the feeling around the word is genuinely mixed, and I would be lying to you if I said otherwise. Some people use Spanglish with pride — it names who they are, at home in two worlds. Others use it as a small insult, meaning "you speak neither language properly," and there are Spanish teachers and language purists who dislike it strongly. So when you meet the word, listen for the speaker's tone before you decide what they mean by it. Grammar note: capital S, always, like Spanish and English. Uncountable — you speak Spanglish, not *a Spanglish. It works as a noun and as a modifier: a Spanglish phrase, a Spanglish song. It is informal; you would not expect it in a formal report except when the report is about language itself. The pattern is a productive one, by the way. English has made Chinglish, Konglish, Singlish, Franglais and Hinglish the same way, and Taiwan has its own version of the phenomenon even if the name never stuck.

西班牙式英語／西英混合語（把西班牙語和英語混著講的說法，美國西語裔常見）。語言學上屬「語碼轉換 code-switching」。注意：中文若直翻成「破英文」會誤導——Spanglish 本身是中性描述，帶不帶貶意要看說話者的語氣。
