Adverbs of Frequency
To talk about how often you do things, you will use adverbs of frequency. Let's start with two very common ones: a veces (sometimes) and nunca (never).
These adverbs usually go right before the verb. If the verb has a pronoun (like me or te), the adverb goes before the pronoun. Notice that when you put nunca before the verb, you do not need to add the word no—the sentence is already negative!
You can easily adjust the frequency by adding casi (almost) to create casi nunca (almost never) and casi siempre (almost always).
Often and Always
To talk about things that happen frequently, use a menudo (often) or siempre (always). While siempre generally stays before the verb, a phrase like a menudo is flexible and can comfortably sit after the verb as well.
Routines and Habits
Once you are comfortable with these adverbs, you can use them to describe your daily schedule, such as your routines (la rutina) and habits (la costumbre).
Every: cada
Cada (each, every) never changes. On its own it goes with a singular noun: cada día, cada semana, cada año. With a number, the noun is plural: cada dos días (every two days), cada ocho horas. Todos los días says almost the same as cada día. On its own, cada uno / cada una means each one.
