เสียจน

So ... That: เสียจน

Level 4

เสียจน can express 'so ... that' or 'to the point that.' The examples connect tiredness, crying, delicious food, or beauty with a result described by the speaker. This is about degree or amount, not only quantity.

How It Works

Connect a Degree With a Result
เสีย has other uses, including meanings associated with loss or damage. In the combination taught here, read เสียจน as an emphatic link to the result that follows. The displayed examples all include a result, but this lesson does not claim that every use in every context must have a fully stated result clause.

Read the Meaning in Context
The examples include tiredness and crying as well as delicious food and beauty. Emphasis does not automatically mean that something is excessive or undesirable. In เหนื่อยเสียจนนอนไม่หลับ, นอน and หลับ are separate predicates: the sentence describes being unable to fall asleep. It does not give a clinical explanation of why tiredness affects sleep.

Compare the Written Patterns
In เธอสวยมากเสียจนผมพูดไม่ออก, มาก comes before เสียจน. That is the order in this example, not a required extra word in every sentence. Compare จนกระทั่ง, which can mark an endpoint or an event reached. This entry does not rank the expressions by formality or frequency, or establish that one is interchangeable with another in every context.

Follow Each Exercise's Request
The first exercise asks you to copy the displayed degree-and-result pattern. The second asks for a plain time endpoint with จนถึง. Those requests distinguish the two answers for these tasks; they do not ban every emphatic description of waiting until a time.

Examples (4)

  1. เหนื่อยเสียจนนอนไม่หลับ

    I was so tired that I couldn't fall asleep.

    Word by Word: tired | emphatic particle | until | lie down | not | fall asleep

    This reading supplies 'I' from context; the Thai sentence does not state a subject. เหนื่อย names tiredness, while นอนไม่หลับ describes being unable to fall asleep. เสียจน connects them in the speaker's account. No medical cause is verified here.

  2. เขาร้องไห้เสียจนตาแดง

    He cried so much that his eyes turned red.

    Word by Word: he | cry | emphatic particle | until | eyes | red

    The sentence presents crying and red eyes as a degree-and-result relationship. 'He' is the English reading used here for เขา; the pronoun alone does not verify a person's gender. This example is not clinical evidence about red eyes.

  3. อาหารร้านนี้อร่อยเสียจนต้องกลับมาทานอีก

    The food at this restaurant is so delicious that I have to come back and eat here again.

    Word by Word: food | shop | this | delicious | emphatic particle | until | must | return | come | eat | again

    The translation supplies 'I' as one contextual reading of the unstated subject of ต้องกลับมาทานอีก. The speaker describes the food's deliciousness as a reason to return. This is the meaning of the example, not a verified assessment of a restaurant or a rule that pleasure obliges everyone to return.

  4. เธอสวยมากเสียจนผมพูดไม่ออก

    She is so beautiful that I am speechless.

    Word by Word: she | beautiful | very | emphatic particle | until | I | speak | not | out

    This reading uses 'she' for เธอ and 'I' for ผม. มาก intensifies สวย and appears before เสียจน in this sentence. พูดไม่ออก describes the speaker's inability to speak in the example. No universal particle order, speaker identity, or factual judgment about beauty follows from it.

Common Mistakes

  • Moving เสีย when copying the displayed pattern.

    เขาเสียเหนื่อยจนนอนไม่หลับ
    เขาเหนื่อยเสียจนนอนไม่หลับ

    For this task, copy เขาเหนื่อยเสียจนนอนไม่หลับ: เหนื่อย comes before เสียจน. The alternative เขาเสียเหนื่อยจนนอนไม่หลับ changes that sequence and does not meet the copying request. This comparison does not set a placement rule for every other use of เสีย.

  • Using the degree-and-result pattern for a task requesting a plain time endpoint.

    ฉันรอเสียจนห้าโมงเย็น
    ฉันรอจนถึงห้าโมงเย็น

    This task requests 'I waited until five in the evening' with the plain endpoint pattern ฉันรอจนถึงห้าโมงเย็น. The alternative ฉันรอเสียจนห้าโมงเย็น does not copy that requested pattern. This exercise does not establish that every emphatic expression of waiting until a time is impossible.

Learn This First

To understand 'เสียจน', you first need to know the basic resultative marker 'จน' (until/to the point that). Since 'เสียจน' emphasizes an extreme degree or intensity that leads to a result, understanding intensity markers like 'มาก' and how Thai structures consequences is essential.
