The word "casa" translates to "house" in English, and "co" can be a preposition meaning "with" in Spanish or Portuguese, but in isolated terms it often appears as part of phrases (for example, "casa" meaning home or house, and "co" as abbreviation or part of proper nouns). If you’re looking for translations or usage in a specific language context, please specify the target language and a sample sentence. If your goal is language learning, here are quick basics:

• Spanish/Portuguese context:
  • casa = house/home
  • co is not a standalone common word in Spanish or Portuguese; in Portuguese, "com" means with, which is similar to the English "with" and is sometimes colloquially shortened or misspelled as "co" in informal writing.
• English equivalents:
  • casa → house, home
  • co → (depends on language; not a standalone English word)
• Common phrases:
  • Spanish: casa bonita = beautiful house
  • Portuguese: casa nova = new house
