背が高い

§ What does it mean and when do people use it?

Let's break down 背が高い (se ga takai). This phrase is how you say 'tall' in Japanese, but specifically for people. You'll hear and use this often when describing someone's height.

DEFINITION

Tall (for a person).

The literal breakdown is interesting:

• 背 (se): This means 'back' or 'stature.' When combined with height adjectives, it refers to a person's overall height.
• が (ga): This is a particle that marks the subject of the sentence. In this case, it connects 'stature' to 'is tall.'
• 高い (takai): This means 'high' or 'expensive.' In the context of height, it means 'high' or 'tall.'

So, '背が高い' literally translates to 'stature is high.' While you might be tempted to use just '高い' (takai) for 'tall,' remember that '高い' can also mean 'expensive' or 'high' in other contexts. For people's height, '背が高い' is the correct and natural phrase.

You'll use 背が高い in everyday conversations when you're talking about someone's physical appearance. For example, if you're describing a new friend or a celebrity, this phrase will come in handy. It's a common and fundamental phrase in Japanese for describing people.

This is a very straightforward use of the phrase. You can also use it in questions:

You'll find this phrase used in all sorts of social situations. Whether you're describing someone you met, a character in a book, or even yourself, 背が高い is the go-to expression. It's polite and commonly understood. For example, if you're talking about a basketball player, you would definitely say:

It's important to note that while 背が高い is specifically for people, if you want to say something like 'the building is tall,' you would use a different adjective like '高い' (takai) directly. So, don't use 背が高い for inanimate objects or things that don't have a 'stature' in the same way a person does.

Another common use is in comparisons. For instance, if you're comparing two people's heights:

This shows its versatility in different sentence structures. It's an essential building block for describing people in Japanese. Master this phrase, and you'll be able to add more detail to your conversations about individuals.

§ Understanding 背が高い (se ga takai)

When you want to describe someone as 'tall' in Japanese, the phrase you'll use most often is 背が高い (se ga takai). It literally translates to 'back is high' or 'stature is high,' which makes sense when you think about someone's height.

It's important to remember that 背が高い is specifically for people. You wouldn't use it to describe a tall building or a tall tree. For those, you'd use just 高い (takai).

§ Basic Sentence Structure

Let's look at how to plug 背が高い into a simple sentence. The basic structure is:

• [Person] は 背が高い です。 (desu - for politeness)
• [Person] は 背が高い。 (casual)

Hint

He is tall.

Hint

She is taller than me.

Notice how we use は (wa) to mark the topic of the sentence. The 'desu' at the end makes it polite. For a casual conversation among friends, you can drop 'desu'.

§ Describing a Noun

You can also use 背が高い to directly describe a noun. In this case, you'll need the particle の (no) to connect it:

• 背が高い の [noun]

Hint

A tall man.

While this is grammatically correct, you'll often hear 背が高い人 (se ga takai hito) which means 'a tall person'. The の particle is frequently omitted when the adjective directly modifies a noun. So, in this case:

• 背が高い人 (se ga takai hito)

Hint

Who is that tall person?

§ Asking About Height

To ask if someone is tall, you can simply add か (ka) to the end of the polite form:

Hint

Is John tall?

And if you want to ask 'how tall' someone is, you'd typically ask about their actual height measurement. We'll cover that in a different lesson, but for now, focus on whether someone is generally 'tall' or not.

§ Negating 'Tall'To say someone is 'not tall,' you need to negate the adjective 高い (takai). The negation of an i-adjective involves changing the い (i) to くない (kunai).

• 背が高くない です。 (polite)
• 背が高くない。 (casual)

私は背が高くないです。

Hint

I am not tall.

So, practice using 背が高い (se ga takai) when talking about people's height. It's a fundamental phrase you'll hear and use often.

§ Don't Use 背が高い for Objects

Many beginners try to use 背が高い for anything that's tall, just like in English. But in Japanese, 背が高い is specifically for people. It literally means 'back is high,' which refers to a person's height. You wouldn't say a building's 'back is high.'

For objects, you need to use different words. The most common one is 高い (takai). This word has multiple meanings, including 'tall' (for objects), 'high,' and 'expensive.' You'll pick up the right usage with practice.

§ Don't Forget the Particle が (ga)

背が高い is an i-adjective, but it's formed from a noun (背) and an adjective (高い). The particle が (ga) is crucial here. It marks 背 (back/height) as the subject of the adjective 高い (tall/high).

DEFINITION

が (ga): A subject particle.

Leaving out が makes the phrase sound unnatural or grammatically incorrect. Think of it as 'his back is high' rather than just 'he is tall.' This helps reinforce why が is there.

§ How to Use It in Questions and Comparisons

When asking about someone's height, you can use 背が高い in a question. For example:

To compare heights, you can use the comparative structure '〜より (yori)'.

§ Other Related Expressions

While 背が高い means 'tall,' here are some related terms for completeness:

• 背が低い (se ga hikui): Short (for a person)
• 高い (takai): Tall/high/expensive (for objects, general height, or price)
• 低い (hikui): Short/low (for objects, general height)

Understanding these distinctions will help you sound more natural and avoid common pitfalls when describing height in Japanese.
