How to Say "thoroughly" in Spanish
The Spanish word for “thoroughly” is “profundamente” — B1 level. This is a very common word in everyday Spanish.

The '-mente' Pattern
This word is an adverb, which means it describes how an action is done. Most Spanish adverbs are formed by adding the ending '-mente' (similar to the English '-ly') to the feminine version of the adjective (profunda + mente).
Overusing 'Muy'
Mistake: “Usar 'muy profundo' para describir un sentimiento.”
Correction: Use 'profundamente' instead. It sounds more natural and eloquent when describing how an action is performed, rather than just using 'very deep.'
