Listen to this. Adverbs often end in lie. Super easy rule. If the adjective is quick, the adverb is quickly. So quick means rápido and quickly means rapidamente. Now pay attention. Some words break the pattern. Fast stays fast. Hard stays hard. Here's the thing. Hardly is different. It means casi no, not duramente. Example, she learns songs quickly, but she sings live fast and works hard. Aprende canciones rapidamente, pero canta en directo rápido y trabaja duro. This is important Don't say fastly or hardly for Duro See you tomorrow Keep going
