How to Say "countless" in Spanish
The most common Spanish word for “countless” is “innumerable” — use this when you want to emphasize that the quantity is extremely large, to the point where counting is impractical or impossible.
innumerable
een-noo-meh-rah-blehinumneˈɾaβle

Examples
Hay innumerables estrellas en el cielo nocturno.
There are countless stars in the night sky.
He leído este libro innumerables veces.
I have read this book countless times.
La investigación reveló innumerables errores en el sistema.
The investigation revealed innumerable errors in the system.
One Form for All
This word ends in 'e', which means it stays the same regardless of whether the person or thing you are describing is masculine or feminine. You only need to add an 's' for plurals.
Adding Emphasis
While many Spanish adjectives go after the noun, placing 'innumerable' before the noun (e.g., 'innumerables estrellas') adds a more poetic or emphatic tone.
Gender Confusion
Mistake: “innumerable mesa / innumerablo libro”
Correction: innumerable mesa / innumerable libro. Words ending in 'e' don't change to 'a' or 'o' to match the gender.
infinito
een-fee-nee-tohin.fi.ˈni.to

Examples
El espacio exterior parece ser infinito.
Outer space seems to be infinite.
Ella tiene una paciencia infinita con los niños.
She has infinite patience with children.
Matching the Noun
This word changes its ending to match the thing it describes. Use 'infinito' for masculine things (el cielo) and 'infinita' for feminine things (la paciencia).
Gender Mismatch
Mistake: “una paciencia infinito”
Correction: una paciencia infinita - because 'paciencia' is a feminine word, 'infinito' must change its ending to 'a'.
