How to Say "constant" in Spanish
The most common Spanish word for “constant” is “constante” — use 'constante' when something is always present or happening, emphasizing its continuous occurrence over time, like a recurring sound or feeling..
constante
kohn-STAHN-teh/konˈstante/

Gender is Easy
Since 'constante' ends in '-e', it doesn't change its ending to match the gender of the person or thing it describes. Use 'el esfuerzo constante' (masculine) and 'la dedicación constante' (feminine).
Always Feminine
When used as a noun meaning a fixed value in math or science, 'constante' is always feminine: 'la constante'.
Confusing Adjective and Adverb
Mistake: “Using 'constante' when you mean 'constantly' (which is the adverb 'constantemente').”
Correction: Remember, 'constante' describes a noun (a constant effort). If you want to describe how an action is done, use the adverb: 'Trabaja constantemente' (He works constantly).
permanente
/per-ma-NEN-te//peɾ.maˈnen.te/
Examples
Necesitamos una solución permanente a este problema.
We need a permanent solution to this problem.
El daño al edificio no es permanente, se puede reparar.
The damage to the building is not permanent; it can be repaired.
Ella tiene un puesto permanente en la universidad.
She has a permanent position at the university.
Always the Same
As an adjective, 'permanente' always keeps the same ending ('-e'), whether it describes a masculine or feminine person or thing (e.g., 'el cambio permanente' and 'la solución permanente').
continua
kohn-TEE-nwah/konˈtinwa/
Examples
La lluvia fue continua durante toda la noche.
The rain was continuous throughout the whole night.

The company requires ongoing improvement of its processes.
En la carretera, una línea continua prohíbe adelantar.
On the road, a continuous line prohibits passing.
Gender Agreement
Since 'continua' is an adjective, it must match the feminine noun it describes (e.g., 'una acción continua'). For masculine nouns, always use 'continuo'.
Confusing Adjective and Verb
Mistake: “Using 'continua' when you mean the verb 'she continues' ('ella continua').”
Correction: The verb form for 'she continues' must have an accent: 'continúa'. 'Continua' (no accent) is only the descriptive word (adjective).

Emphasis Placement
When 'eterno' is used figuratively (meaning 'constant' or 'always present'), it often goes before the noun, like in 'el eterno dilema' (the constant dilemma).
Confusing 'Constant' and 'Forever'
Mistake: “Using 'eterno' when you just mean 'frequent' or 'long'.”
Correction: Use 'largo' (long) or 'frecuente' (frequent) unless you want the strong exaggeration 'eterno'.
