esté

VerbA2Formal/Subjunctive
Use 'esté' when giving a formal command to one person to 'be' a certain way, or when expressing a wish, doubt, or emotion about a singular 'you' or 'he/she/it' (subjunctive mood).

Examples

Espero que usted esté bien.

I hope that you are well.

sea

/SEH-ah//ˈse.a/

VerbA2Formal/Subjunctive
Use 'sea' for formal commands to one person to 'be' a certain way, or when expressing a wish, doubt, or emotion about a singular subject like 'the party' or 'the situation' (subjunctive mood).
A person looking hopefully at a sky that could be sunny or cloudy, representing the uncertainty or wishful thinking where 'sea' is used.

Examples

Por favor, sea puntual.

Please, be punctual.

Espero que la fiesta sea divertida.

I hope the party is fun.

No creo que sea una buena idea.

I don't think it's a good idea.

Busco un trabajo que sea interesante.

I'm looking for a job that is interesting.

The 'Maybe' Mood (Subjunctive)

'Sea' is a special form of 'ser' (to be) used when you're not stating a fact. You use it to talk about wishes, doubts, possibilities, or opinions. Think of it as the 'what if' or 'I hope so' form of 'to be'.

Polite Commands (Imperative)

Use 'sea' to give a polite command to someone you address as 'usted' (the formal 'you'). It's the command form of 'ser' (to be). For example, 'Sea honesto' means 'Be honest'.

Using 'es' instead of 'sea'

Mistake: “No creo que es verdad.”

Correction: No creo que **sea** verdad. After phrases that express doubt like 'no creo que' (I don't think that), Spanish uses this special 'sea' form to show it's not a sure thing.

Mixing up 'sé' and 'sea'

Mistake: “When talking to a friend: 'Sea bueno'.”

Correction: To a friend (using the 'tú' form), the command is '**sé** bueno'. You use '**sea** bueno' when speaking to someone more formally (using the 'usted' form).

sean

/seh-ahn//ˈse.an/

VerbA2Formal/Subjunctive
Use 'sean' when expressing a wish, doubt, or emotion about multiple people ('they' or 'you all' - formal) or when giving a formal command to a group to 'be' a certain way.
Three diverse children standing together, smiling joyfully, illuminated by a large, bright, floating golden star, symbolizing a wish or hope.

Examples

Espero que sean felices en su nueva casa.

I hope they are happy in their new house.

No creo que los resultados sean tan malos.

I don't think the results are that bad.

Para mí, es importante que ustedes sean honestos.

For me, it's important that you all are honest.

Por favor, sean puntuales para la reunión.

Please, be punctual for the meeting.

The 'Maybe' Verb Form (Subjunctive)

In Spanish, when you talk about things that aren't definite facts—like wishes, doubts, emotions, or possibilities—you often need a special verb form. 'Sean' is this special form for 'they' and 'you all'.

Trigger Words

Look for phrases like 'espero que' (I hope that), 'no creo que' (I don't think that), and 'es importante que' (it's important that). These are strong clues that you'll need to use 'sean' instead of 'son'.

Giving a Command to a Group

'Sean' is how you give a command to a group of people you are addressing as 'ustedes'. This is used everywhere for formal situations, and in Latin America for all group commands.

Using 'Son' Instead of 'Sean'

Mistake: “Espero que son felices.”

Correction: Espero que sean felices. After a 'trigger' phrase like 'espero que', the verb changes to show it's a wish, not a fact.

Using 'Ser' for a Command

Mistake: “Ustedes, ser amables.”

Correction: Ustedes, sean amables. To give a command, you have to use the special imperative form, not the basic 'ser' form.

sé

VerbA2Informal Command
Use 'sé' when giving a direct, informal command to one person ('you') to 'be' a certain way.

Examples

Sé amable con tu hermano.

Be kind to your brother.

Formal vs. Informal Commands and Subjunctive Mood

The most common confusion is between formal commands ('esté', 'sea', 'sean') and informal commands ('sé'). Remember that 'sé' is always an informal command to 'tú' (you, singular). The others ('esté', 'sea', 'sean') are used for formal commands ('usted', 'ustedes') or in subjunctive clauses expressing wishes or doubts.
