Questions & Answers about Tôi nghe còi ở tiệm sửa xe.

What does tôi mean here, and is it always necessary?

Tôi means I.

It is the most neutral, standard way to say I in Vietnamese, especially in textbooks and when speaking politely to people you do not know well.

In real life, Vietnamese often uses kinship-style pronouns instead of tôi, depending on age, relationship, and situation. For example, a speaker might say mình, em, anh, chị, etc.

You can sometimes omit tôi if the subject is already clear from context, but in a standalone sentence like this, keeping tôi makes it complete and natural.

What does nghe mean, and why is it used instead of something else?

Nghe means to hear or to listen.

In this sentence, it means hear in the general sense of perceiving a sound.

A useful comparison:

• nghe = hear / listen
• nghe thấy = hear, with extra emphasis that the sound was actually perceived
• lắng nghe = listen carefully / attentively

So:

• Tôi nghe còi ở tiệm sửa xe. = I hear a horn/siren at the repair shop.
• Tôi nghe thấy còi ở tiệm sửa xe. = I can hear a horn/siren at the repair shop.

Both can work, but nghe is shorter and very common.
