How to Say "significant" in Spanish
The most common Spanish word for “significant” is “importante” — use 'importante' when referring to something that has great consequence, importance, or is generally considered a big deal..
importante
/eem-por-TAHN-teh//impoɾˈtante/

Examples
Es muy importante estudiar.
It's very important to study.
Tengo una reunión importante mañana.
I have an important meeting tomorrow.
Él es una figura importante en la política local.
He is an important figure in local politics.
Same for Everyone
Importante ends in '-e', which is great news! It means you use the same form for both masculine and feminine things. For example: 'el libro importante' (the important book) and 'la casa importante' (the important house).
Placement is Key
Usually, importante comes after the thing it describes, just like in English. For example, 'una reunión importante' (an important meeting). Placing it before ('una importante reunión') adds a bit of emphasis or a more formal tone.
Your Go-To Verb: 'ser'
To say something is important, you'll almost always use the verb 'ser'. For example, 'Ser honesto es importante' (Being honest is important).
The 'Es importante que...' Rule
Mistake: “Es importante que tú estudias mucho.”
Correction: Es importante que tú estudies mucho. When you say it's important for *someone else* to do something, the verb that follows needs a special ending. This is a huge pattern in Spanish!
relevante
/reh-leh-BAHN-teh//releˈβante/

Examples
Tu opinión es muy relevante para este proyecto.
Your opinion is very relevant to this project.
No encontré ninguna información relevante en el informe.
I didn't find any relevant information in the report.
Es un cambio pequeño, pero relevante.
It's a small but significant change.
One ending for all
This word is the same whether you are talking about a man, a woman, a masculine object, or a feminine object. It always ends in -e.
Mistaking with 'Importante'
Mistake: “Using 'importante' when you specifically mean 'connected to the topic.'”
Correction: While 'importante' works for general importance, use 'relevante' to show that something specifically applies to the current situation or discussion.
notable
/noh-TAH-bleh//noˈtaβle/

Examples
Hubo una mejoría notable en sus notas este trimestre.
There was a remarkable improvement in his grades this term.
La diferencia de precio es notable.
The difference in price is noticeable.
One Form for All
This word ends in -e, which means it stays the same whether you are describing a masculine or feminine person or thing. You say 'un cambio notable' and 'una mejoría notable'.
sensible
/sen-SEE-bleh//senˈsible/

Examples
La empresa experimentó un aumento sensible en sus ventas después de la campaña.
The company experienced a noticeable increase in its sales after the campaign.
Hubo una mejora sensible en la calidad del sonido.
There was a significant improvement in sound quality.
Describing Data
This meaning is often used when discussing statistics, data, or technical results, emphasizing that the change is large enough to matter or be easily perceived.
razonable
rah-thoh-NAH-bleh (Spain) / rah-soh-NAH-bleh (L. Am.)/raθoˈnaβle/

Examples
El proyecto requirió un esfuerzo razonable de todo el equipo.
The project required a considerable effort from the entire team.
Hemos visto un avance razonable en las negociaciones.
We have seen moderate/significant progress in the negotiations.
Quantifier
In this meaning, 'razonable' acts like a quantifier, emphasizing that the amount or degree was sufficient or impressive, not just 'sensible'.
Don't confuse 'importante' with 'relevante'
