How to Say "undeniable" in Spanish
The most common Spanish word for “undeniable” is “indudable” — use 'indudable' when something is clearly true and cannot realistically be argued against, like a proven fact..
indudable
/een-doo-dah-bleh//induˈdaβle/

Examples
Es un hecho indudable que el clima está cambiando.
It is an undeniable fact that the climate is changing.
Su talento para el piano es indudable.
Her talent for the piano is unquestionable.
Existe un riesgo indudable en esta decisión.
There is a certain risk in this decision.
One Word for Both Genders
This word ends in 'e,' so it doesn't change whether you are describing a masculine or feminine thing. You can say 'un hecho indudable' or 'una verdad indudable'.
Emphasizing with Word Order
Usually, you put this word after the thing it describes. If you put it before (e.g., 'el indudable éxito'), it sounds much more poetic or dramatic.
Don't change the ending to 'o'
Mistake: “El resultado es indudablo.”
Correction: El resultado es indudable. Words ending in -able always end in -e regardless of gender.
indiscutible
/een-dees-koo-TEE-blay//indiskuˈtiβle/

Examples
Su talento para la música es indiscutible.
Her talent for music is unquestionable.
Es un hecho indiscutible que el clima está cambiando.
It is an indisputable fact that the climate is changing.
El equipo obtuvo una victoria indiscutible en la final.
The team achieved an undeniable victory in the final.
One Form for All
This word ends in -e, which means it doesn't change its ending for masculine or feminine. You can say 'un hombre indiscutible' or 'una mujer indiscutible' and it stays exactly the same.
Placement for Emphasis
While most adjectives go after the noun, putting 'indiscutible' after the noun (e.g., 'un talento indiscutible') is standard, but placing it before the noun (e.g., 'su indiscutible talento') adds a more poetic or dramatic emphasis to the quality.
The 'Indiscutibla' Error
Mistake: “La verdad es indiscutibla.”
Correction: La verdad es indiscutible. Remember that adjectives ending in -e are neutral and do not change to -a for feminine nouns.
