💡 Grammar Points
Agreement is Key
Since 'unidas' ends in -as, it must describe two or more feminine things or people. If you were describing two masculine things (e.g., 'los equipos'), you would use 'unidos'.
Adjective or Participle?
'Unidas' is the past participle of the verb 'unir' (to unite). When it follows 'ser' or 'estar,' it acts like an adjective, describing the resulting state ('Las piezas están unidas').
❌ Common Pitfalls
Incorrect Gender/Number
Mistake: "Los países están unidas."
Correction: Los países están unidos. ('Países' is masculine plural, so use 'unidos'.)
⭐ Usage Tips
Focus on State
Use 'estar unidas' to talk about the current state of being joined or in agreement, and 'ser unidas' (often in the passive voice) to describe the action of being joined.
