Daily Thai Confidence: Using ตรวจ (dtrùad)

Verb: ตรวจ (dtrùad)
Meaning: to check / to inspect / to examine / to verify

In this Thai lesson, we learn how to use the verb ตรวจ (dtrùad), which means ‘to check,’ ‘to inspect,’ ‘to examine,’ or ‘to verify’. It is used when someone looks carefully at something to make sure it is correct, safe, or in good condition.

The typical structure usually follows the pattern: subject + ตรวจ (dtrùad) + noun.

For examples (ตัวอย่างเช่น — dtūa-^awyàang chên)

k^hrūu dtrùad gāan-bâan
Literal: Teacher check homework.
The teacher checks the homework.

In this sentence, the verb ตรวจ (dtrūad) means ‘to check’ or ‘to review for correctness’. It refers to the teacher looking at students’ homework carefully to find mistakes, assess accuracy, or evaluate their work. The focus here is on checking for errors and giving feedback, rather than just looking at it.

chǎn dtrùad dtǔa gàwn k^hêun ród-fāi
Literal: I check ticket before get on train.
I check the ticket before boarding the train.

In this sentence, the verb ตรวจ (dtrūad) means ‘to check’ or ‘to verify’. It refers to looking at the ticket carefully to make sure everything is correct, such as the time, seat, or destination. The action is done before boarding the train to avoid any problems.

^hmǎw dtrùad āa-gāan k^hǎwng-k^hǎo ^awyàang-lá-ìad
Literal: Doctor check symptom belonging to-him carefully.
The doctor examined his symptoms carefully.

In this sentence, the verb ตรวจ (dtrūad) means ‘to examine’ or ‘to check carefully’. It is used in a medical context, where a doctor looks closely at a patient’s condition to understand what is wrong. The word emphasises a careful and professional examination, not just a quick look.

k^hūn k^hūan dtrùad sùk-k^hà-p^hâab t^húk bpēe
Literal: You should check health every year.
You should have a health check-up every year.

In this sentence, the verb ตรวจ (dtrūad) means ‘to examine’ or ‘to have a medical check-up’. It is used in a health context, referring to a doctor checking your body to assess your overall health and detect any potential problems. The phrase ตรวจสุขภาพ (dtrūad sùk-k^hà-p^hâab) specially means ‘to have a health check-up’.
