Words that describe how, when, where, why, or to what extent—how often or how much (e.g., daily, completely). In English these often end in “ly”. So for example, quickly, easily, mainly, totally, freely, and so on.
Most of these are formed by adding “mente” to the verb stem.totally > totalmente
Sua ideia é totalmente brilhante. (totally)
Isso aconteceu facilmente demais. (easily)
Não tenho escrito muito ultimamente. (lately)
