💡 Grammar Points
Feminine Form
When referring to a female opponent, the word changes to 'enemiga'. Both are nouns: 'El enemigo' (the male enemy) or 'La enemiga' (the female enemy).
The Personal 'a'
If you are talking about seeing or knowing a specific person who is an enemy, you must use the little word 'a' before them: 'Conocí a mi enemigo' (I met my enemy).
❌ Common Pitfalls
Mixing Noun and Adjective
Mistake: "La persona es enemigo."
Correction: La persona es enemiga. (Remember to match the gender, 'enemiga' for a female person, or 'enemigo' if you mean the team/group is the enemy.)
⭐ Usage Tips
Beyond People
You can use 'enemigo' figuratively for abstract concepts or problems, like 'El tiempo es nuestro enemigo' (Time is our enemy).

If someone is described as enemigo (hostile), they are opposed or aggressive.

💡 Grammar Points
Matching the Noun
As an adjective, 'enemigo' must match the gender and number of the noun it describes. For example, 'fuerzas' (forces) is feminine plural, so you say 'fuerzas enemigas'.
❌ Common Pitfalls
Using the Singular
Mistake: "Llegaron los barcos enemigo."
Correction: Llegaron los barcos enemigos. (Since 'barcos' is plural, the adjective must also be plural.)
⭐ Usage Tips
Positioning
The adjective usually comes after the noun it describes: 'un ejército enemigo' (a hostile army), reinforcing the description.
