How to Say "hard" in Spanish
The most common Spanish word for “hard” is “difícil” — use this when referring to something that requires effort or is challenging to understand or accomplish, like a task or a concept..
difícil
dee-FEE-seel (Remember the stress is on the second 'i'!)/diˈfi.sil/

Examples
Aprender español no es difícil, pero requiere práctica.
Learning Spanish is not difficult, but it requires practice.
Resolver este problema de matemáticas fue muy difícil.
Solving this math problem was very hard.
Tuvieron un viaje difícil debido a la tormenta.
They had a difficult trip because of the storm.
Agreement in Number
Since 'difícil' is an adjective, it must match the thing it describes. For a plural noun, add '-es': 'las cosas difíciles' (the difficult things).
Forgetting Plural Agreement
Mistake: “Los exámenes es difícil.”
Correction: Los exámenes son difíciles. (The exams are difficult.) Remember to add -es for plural nouns.
duro
/DOO-roh//ˈdu.ɾo/

Examples
Esta piedra es muy dura.
This stone is very hard.
El pan de ayer está duro.
Yesterday's bread is stale.
Ha sido un año muy duro para nosotros.
It has been a very difficult year for us.
Tenemos que trabajar duro para terminar a tiempo.
We have to work hard to finish on time.
Matching the Noun
As an adjective, 'duro' changes to match the thing it describes. Use 'dura' for feminine things ('la cama dura'), 'duros' for plural masculine ('los panes duros'), and 'duras' for plural feminine ('las pruebas duras').
Always Stays the Same
When 'duro' describes how an action is done (like in 'trabajar duro'), it's an adverb. This means it NEVER changes. It's always 'duro', never 'dura' or 'duros'.
Confusing with 'Difícil'
Mistake: “'Duro' can mean 'difficult', but 'difícil' is often a better choice for abstract challenges like exams or problems.”
Correction: Use 'un examen difícil' (a difficult exam) instead of 'un examen duro'. 'Duro' implies more of a struggle or hardship.
Making it Match
Mistake: “Mi hermana trabaja dura.”
Correction: Say 'Mi hermana trabaja duro.' Because 'duro' here describes *how* she works, not her as a person, it doesn't change.

The Adjective-Adverb Shortcut
In Spanish, some words that look like adjectives can describe how an action is done. 'Fuerte' is a great example. Instead of always saying the longer 'fuertemente', people often just say 'fuerte'. It doesn't change its ending.
rudo
