💡 Grammar Points
Adjective Agreement
Like most Spanish adjectives, 'efectivo' must match the noun it describes in both gender (masculine/feminine) and number (singular/plural). For example: 'solución efectiva' (feminine singular) or 'resultados efectivos' (masculine plural).
❌ Common Pitfalls
Confusing Adjective and Noun
Mistake: "Using 'el efectivo' to mean 'the effective one' when describing a feminine noun."
Correction: Always use 'efectiva' if the noun is feminine (e.g., 'la técnica efectiva'). The noun 'el efectivo' always means 'cash'.
⭐ Usage Tips
Emphasizing Reality
When 'efectivo' means 'actual' or 'real,' it often emphasizes the difference between what was planned or assumed and what truly happened.

The noun efectivo refers to 'cash' or physical money, including bills and coins.

💡 Grammar Points
Always Masculine
When used as a noun meaning 'cash,' 'efectivo' is always masculine singular ('el efectivo'), even though it refers to many bills and coins.
❌ Common Pitfalls
Using 'Efectivos' (Plural)
Mistake: "Saying 'Necesito unos efectivos' to mean 'I need some cash.'"
Correction: The noun 'efectivo' is usually uncountable, so use 'Necesito efectivo' or 'un poco de efectivo.' The plural 'efectivos' refers to personnel or troops (military/police), not money.
⭐ Usage Tips
The Preposition 'En'
When describing the method of payment, always use the preposition 'en': 'Pagar en efectivo' (to pay in cash).

Frequently Asked Questions
What is the difference between 'efectivo' (noun) and 'dinero'?
'Dinero' is the general word for 'money.' 'Efectivo' is specifically the physical form of money—bills and coins—as opposed to digital payments, checks, or credit.
How do I say 'in effect' or 'in force' (like a rule)?
You would typically use the phrase 'en vigor' or 'en efecto' (using the related noun 'efecto'), not 'en efectivo,' which only means 'in cash.'
