Si el café está muy amargo, echa una cucharadita de azúcar.

Si means if.

In this sentence, it introduces a condition:

• Si el café está muy amargo... = If the coffee is very bitter...

A very common pattern in Spanish is:

• si + present tense, then
• a result in the present, future, or an imperative

Here, the result is a command:

• echa una cucharadita de azúcar = add a teaspoon of sugar

So the structure is completely normal:

• Si + present, imperative

It uses está because Spanish normally uses estar for a state or condition at that moment.

• El café está muy amargo = the coffee tastes very bitter / the coffee is very bitter right now

Using es would sound odd here, because bitterness is being treated as the current condition of this particular coffee, not as its permanent identity.

A useful way to think about it:

• ser = what something is
• estar = how something is

Taste descriptions for a specific serving often use estar:

• La sopa está salada = The soup is salty
• El té está frío = The tea is cold

Amargo means bitter.

In food and drink contexts, it describes an unpleasantly bitter taste:

• café amargo = bitter coffee

It can also be used more generally in Spanish for figurative meanings like bitter or painful, but here it is just about taste.

Related taste words:

• dulce = sweet
• salado = salty
• ácido = acidic / sour
• picante = spicy

Echa is the tú imperative (informal singular command) of echar.

The infinitive is:

• echar = to throw, to pour, to add, to put in

So:

• echa = add! / put in! / pour in!

In this sentence, it means:

• echa una cucharadita de azúcar = add a teaspoon of sugar

This is the command you would use when speaking informally to one person.

Other command forms:

• eche = formal singular (usted)
• echad = informal plural in Spain (vosotros)
• echen = formal plural (ustedes)

Because it is just the normal imperative form of echar, and it does not need a written accent.

Compare:

• echa = add / pour / throw
• está = is

Está has an accent because it is a form of estar and the written accent is part of the standard spelling.

This is also a useful spelling distinction:

• echa = from echar
• hecha = feminine form of hecho, from hacer

So:

• echa azúcar = add sugar
• está hecha = it is done / made

Because in Spanish, quantities are normally followed by de before the substance or thing being measured.

So:

• una cucharadita de azúcar = a teaspoon of sugar
• un vaso de agua = a glass of water
• un kilo de arroz = a kilo of rice

This is very standard Spanish structure:

• quantity/container + de + noun

Cucharadita means teaspoon or literally little spoonful.

It comes from:

• cuchara = spoon
• -dita = a diminutive ending, giving the idea of something smaller

So cucharadita often refers to:

• a small spoon
• a teaspoonful

In recipes and everyday speech, it commonly means a teaspoon.

Compare:

• cuchara = spoon
• cucharada = tablespoon / spoonful
• cucharadita = teaspoon / little spoonful

Spanish often uses the definite article more than English does.

Here, el café means:

• the coffee
• or more naturally in context, the coffee we’re talking about

Even when English might say just coffee, Spanish often prefers an article:

• El café está frío
• La sopa está buena

It makes the noun sound specific: this coffee, this cup of coffee, the coffee in front of you.

In most everyday situations, está muy amargo is the better choice.

That is because you are talking about how this coffee tastes right now.

Using es is not the usual way to describe the taste of a particular cup in front of you. A native speaker would normally say:

• El café está amargo
• La sopa está salada

So while a learner might be understood, está is the natural option here.

Yes. Depending on context, Spanish speakers might also say:

• añade una cucharadita de azúcar = add a teaspoon of sugar
• pon una cucharadita de azúcar = put in a teaspoon of sugar

But echar is very common in Spain for putting something into food or drink:

• echar azúcar al café
• echar sal
• echar aceite

So echa sounds very natural in Spain Spanish.

Because muy is used before adjectives and adverbs.

Here, amargo is an adjective, so you say:

• muy amargo = very bitter

You would not say mucho amargo here.

Quick comparison:

• muy + adjective/adverb
  
  • muy amargo
  • muy rápido
• mucho/a/os/as + noun
  
  • mucho azúcar
  • mucha agua

Yes. Adjectives in Spanish usually agree with the noun they describe in gender and number.

Here:

• café is masculine singular
• so the adjective is amargo

Examples with other nouns:

• La sopa está amarga = The soup is bitter
• Los cafés están amargos = The coffees are bitter
• Las bebidas están amargas = The drinks are bitter

So if the noun changes, the adjective usually changes too.

Because after a measure expression, Spanish usually uses just de + noun when talking about a substance in a general sense.

So:

• una cucharadita de azúcar
• un vaso de agua
• una taza de café

You would not normally say:

• una cucharadita del azúcar

That would mean something more specific, like a teaspoon of the sugar (a particular sugar already identified), which is not what this sentence means.

Here it simply means a teaspoon of sugar in general.

Grammatically, it is an imperative, so it is a command:

• echa una cucharadita de azúcar

But in real-life use, it often sounds more like practical advice or an instruction than a harsh order.

So depending on tone, it could mean:

• add a teaspoon of sugar
• you should add a teaspoon of sugar

Spanish imperatives are used a lot in recipes, instructions, and everyday suggestions.

The comma separates the if-clause from the main clause:

• Si el café está muy amargo,
• echa una cucharadita de azúcar.

This is also common in English:

• If the coffee is very bitter, add a teaspoon of sugar.

It helps show the pause between the condition and the result.

Yes, but it becomes a different word.

• si = if
• sí = yes or oneself

In this sentence, it must be si without an accent because it means if.

Examples:

• Si llueve, no salgo. = If it rains, I’m not going out.
• Sí, claro. = Yes, of course.

This is a very common spelling point for learners.

Yes, only the command form would change.

Current sentence:

• Si el café está muy amargo, echa una cucharadita de azúcar.
• informal singular (tú)

Formal singular:

• Si el café está muy amargo, eche una cucharadita de azúcar.

Informal plural in Spain (vosotros):

• Si el café está muy amargo, echad una cucharadita de azúcar.

Formal plural:

• Si el café está muy amargo, echen una cucharadita de azúcar.

The rest of the sentence stays the same.
