completamente
/kom-pleh-tah-men-teh//komˌple.taˈmen.te/

What is an Adverb?
Words like 'completamente' are adverbs. They describe how an action is done or add intensity to another word. Think of them as adding detail, like saying 'run quickly' instead of just 'run'.
The '-mente' Trick
In Spanish, you can often turn an adjective (a describing word) into an adverb by adding '-mente' to the end of its feminine form. 'Completa' (complete) becomes 'completamente' (completely). It's just like adding '-ly' in English!
Placement Matters
Mistake: “Using 'completo' instead of 'completamente'. For example, 'Estoy completo seguro.'”
Correction: The correct way is 'Estoy completamente seguro.' You need the '-mente' ending to describe *how* you feel (completely sure), not just to describe a thing.
totalmente
/toh-tahl-men-teh//toˌtalˈmente/

Examples
La habitación estaba totalmente a oscuras.
The room was completely dark.
Olvidé totalmente que hoy era tu cumpleaños.
I totally forgot that today was your birthday.
El proyecto está totalmente terminado.
The project is fully finished.
What is an Adverb?
An adverb is a word that describes an action (verb) or adds more detail to a descriptive word (adjective). 'Totalmente' tells you 'how much' or 'to what extent' something is done or is.
Making '-mente' Adverbs
In Spanish, you can turn many descriptive words into adverbs by adding '-mente'. Just take the feminine form of the word and add '-mente'. For example, 'total' (which is the same for masculine and feminine) becomes 'totalmente'.
Word Order
Mistake: “Estoy de acuerdo totalmente.”
Correction: Estoy totalmente de acuerdo. While the first version isn't strictly wrong, it's much more natural to place 'totalmente' right before the word it's describing ('de acuerdo').
