Adverbs Stay the Same
In Spanish, words ending in '-mente' are always the same. You don't need to change them to match masculine or feminine nouns because they describe the action (the verb), not the person.
The '-ly' Connection
The ending '-mente' is the Spanish equivalent of the English '-ly'. You can turn many adjectives into adverbs by taking the feminine form (dura) and adding '-mente'.
Using 'duro' vs. 'duramente'
Mistake: “Él trabaja duramente.”
Correction: Both 'Él trabaja duro' and 'Él trabaja duramente' are correct, but 'duro' is more common in casual conversation, while 'duramente' sounds a bit more formal or dramatic.
