💡 Grammar Points
Agreement is Key
As an adjective, 'construido' must change its ending to match the thing it describes. For a feminine noun like 'mesa' (table), you use 'construida'. For plural nouns like 'puentes' (bridges), you use 'construidos'.
❌ Common Pitfalls
Forgetting Gender Match
Mistake: "La pared es construido."
Correction: La pared es construida. (Since 'pared' is feminine, the adjective must end in -a.)
⭐ Usage Tips
Describing Quality
Use 'construido' with adverbs like 'sólidamente' (solidly) or 'rápidamente' (quickly) to describe the manner in which something was made.

As a verb form (past participle), construido refers to the action of having built something, signifying completion.

💡 Grammar Points
The 'Haber' Team
When 'construido' works with the verb 'haber' (to have), it never changes its ending—it always stays 'construido', regardless of who did the building or what was built. (e.g., 'Yo he construido', 'Ellas han construido').
The Passive Voice
When 'construido' works with the verb 'ser' (to be) to show that something received the action (passive voice), it acts like an adjective and must agree in gender and number. (e.g., 'Las torres fueron construidas').
❌ Common Pitfalls
Changing the Participle with 'Haber'
Mistake: "Hemos construidas las casas."
Correction: Hemos construido las casas. (The participle doesn't change when used with 'haber'.)
⭐ Usage Tips
Focus on the Result
Use the perfect tenses (with 'haber') when you want to emphasize that the action of building is finished and the result is relevant right now.
