How to Say "knowledge" in Spanish
The most common Spanish word for “knowledge” is “conocimiento” — use this for general information, facts, or the state of knowing something acquired through study or experience..
conocimiento
ko-no-see-MYEN-toh/konoθiˈmjento/

Examples
El conocimiento es poder.
Knowledge is power.
Ella tiene un profundo conocimiento de la historia europea.
She has a profound understanding of European history.
La ciencia busca generar nuevo conocimiento.
Science seeks to generate new knowledge.
Always Masculine
Even though it ends in '-a' sound, conocimiento is always masculine: 'el conocimiento'. Most Spanish nouns ending in -miento are masculine.
Conocer vs. Saber
This noun comes from the verb conocer (to know a person, place, or be familiar with something). For factual knowledge, conocimiento works for both conocer and saber concepts.
Using the wrong article
Mistake: “La conocimiento es importante.”
Correction: El conocimiento es importante. (Remember, it's masculine, so use 'el' or 'un'.)
ciencia
SYEN-see-ah (Latin America) or thee-EN-thee-ah (Spain)/ˈsjen.sja/

Examples
No podemos saber a ciencia cierta quién fue el culpable.
We cannot know for certain who the culprit was.
Ese carpintero tiene mucha ciencia en el manejo de la madera.
That carpenter has great skill in handling wood.
Idiomatic Use
This meaning of 'ciencia' is almost exclusively used in the fixed phrase 'a ciencia cierta' to express certainty or lack thereof.
saber
/sa-ber//saˈβeɾ/

Examples
El saber no ocupa lugar.
Knowledge takes up no space.
Es un hombre de mucho saber.
He is a man of great knowledge.
sabiduría
Examples

luces
/loo-ses//ˈlu.θes/ (Spain) or /ˈlu.ses/ (Latin America)

Examples

We need to turn on the lights before it gets dark.
Las luces de la ciudad son impresionantes desde aquí.
The city lights are impressive from up here.
Ese niño tiene muchas luces para su edad.

Gender and Number
This word is the plural form of the feminine noun 'luz' (light). Even though it ends in -es, you use feminine words (like 'las') before it.
Using the wrong plural form
Mistake: “Using 'luzs' instead of 'luces'.”
Correction: When a singular noun ends in 'z' (like luz), you change the 'z' to 'c' and add 'es' to make it plural (luces).
