Adverbs ending in -mente

In english adverbs often end in ly (quickly, slowly, reluctantly). In spanish they often end in -mente.

Add -mente to the feminine form of the adjective.
Ex: desafortunado/desafortunada - Desafrotunadamente, no.
Unfortunately, no.

If the adjective doesn't have a feminine form, then attach it to the singular form.
Ex: frecuente - Yo ablo frecuentemente.
I speak often.

And don't forget accents! They go exactly where they would without the -mente.
Fácil = fácilmente.
