💡 Grammar Points

The '-mente' Rule

In Spanish, words ending in '-mente' are usually adverbs (like English words ending in '-ly'). They are formed by taking the feminine form of an adjective (like 'accidental') and adding '-mente'.

❌ Common Pitfalls

Adverb Placement

Mistake: "Puse accidentalmente el libro en la mesa."

Correction: Accidentalmente puse el libro en la mesa. (Correction: While the adverb can sometimes be placed mid-sentence, placing it before the verb or at the beginning of the sentence often sounds more natural in Spanish.)

⭐ Usage Tips

Quick Alternative

For simple accidents, many native speakers use the phrase 'sin querer' (without wanting to) instead of the longer word 'accidentalmente'.

Frequently Asked Questions

How do I form other Spanish adverbs like 'accidentalmente'?
