Spanish and English are full of cognates, or very similar words that mean the same thing in both languages. Autobus in Spanish, for example, means exactly the same as a very similar English word: Bus. Notorio in Spanish means the same thing as its English twin, notorious.
Assuming a Spanish word means the same thing as a very similar English word is one of the most common mistakes in Spanish (for foreign speakers) and, while you can often get away with it, rest assured that assuming words are cognates will get you into trouble eventually. Take embarazada: A man who uses this word, thinking it means embarrassed, will be embarrassed because it actually means "pregnant".
