The Nikhahit Mark

Level 6

นิคหิต is the small circle ํ above a consonant. Traditional descriptions of Thai vowel shapes use it in ำ and ึ. In the Pali example, it appears as its own mark, distinct from ฺ below a consonant.

How It Works

1. Recognize the Shapes
The open circle Nikhahit ( ํ ) is described in Thai teaching as part of the written forms ำ and ึ. In ำ, the circle appears above the consonant and the stroke า to its right. In ึ, it belongs to the vowel shape above the consonant. This description of visible parts does not mean typing ึ as ิ followed by standalone ํ. Unicode encodes ำ as U+0E33, ึ as U+0E36, and standalone ํ as U+0E4D.

2. Read the Sounded Ending
In the displayed words น้ำ and ดำ, ำ includes a final m sound. คำ likewise ends in m, so use the live-syllable pattern together with the consonant class and any tone mark when applying tone rules. Do not classify this ending as dead merely because a separate ม is not written. Vowel duration and the written shape are separate questions; the live classification here follows the final nasal sound.

3. Compare the Stored Sequences
For the sara-am sequence in น้ำ, the order taught here is น + ้ + ำ: consonant, tone mark, then sara am. Unicode rendering places the circle belonging to ำ below the preceding tone mark. With sara ue in the exercise’s illustrative sequence น + ึ + ้, the vowel character precedes the tone mark. These are stored-character sequences, not a promise about every keyboard’s tap order or automatic correction. The exercise’s reference to older systems does not restrict this distinction to an older Unicode version, and its นึ้ sequence illustrates ordering rather than introducing a vocabulary word.

4. Distinguish the Pali Marks
In พุทฺธํ สรณํ คจฺฉามิ, the circle ํ above ธ and ณ is nikhahit. The point ฺ below ท and จ is phinthu, the virama used in Thai-script Pali to remove a consonant’s inherent vowel. They have different positions and functions. The complete phrase means “I go to the Buddha for refuge.” This example shows the written marks; it does not establish one universal Sanskrit or Thai chanting pronunciation. In the separate interview example, สัมภาษณ์ is written with ม, not with standalone ํ; learn that present spelling without deriving a complete borrowing or nasal-assimilation rule from this one word.

Examples (3)

  1. ฉันชอบดื่มน้ำดำ

    I like drinking dark-colored water.

    Word by Word: I like drink water black

    The displayed sentence contains น้ำ and ดำ, both written with ำ. It does not identify a particular cola or coffee; the literal gloss keeps water and black as separate words.

  2. เขาไปสัมภาษณ์งาน

    He goes for a job interview.

    Word by Word: He go interview work

    In the current Thai spelling สัมภาษณ์, the first syllable is written with final ม rather than standalone ํ. This example is not itself a complete historical derivation or a rule for every Pali/Sanskrit borrowing.

  3. พุทฺธํ สรณํ คจฺฉามิ

    I go to the Buddha for refuge.

    The Pali refuge formula shows standalone ํ in พุทฺธํ and สรณํ, distinct from the virama ฺ in พุทฺธํ and คจฺฉามิ. Read the written marks as different signs; no chanting audio or universal pronunciation is supplied here.

Common Mistakes

  • Using the sara-am stored order for the sara-ue illustration, or reversing the requested sara-am sequence.

    Typing น + ำ + ้ on older systems, or typing น + ้ + ึ for นึ้.
    Typing น + ้ + ำ (traditional for sara am) and น + ึ + ้ (for sara ue).

    The task asks for stored sequences: น + ้ + ำ for sara am, and น + ึ + ้ for the sara-ue illustration. The incorrect row reverses one of those orders. A keyboard may process input; this exercise compares the requested character order, not every device’s behavior or a meaningful word นึ้.

  • Classifying the final m sound in คำ as a dead ending.

    Applying dead syllable rules to คำ.
    Applying live syllable rules to คำ.

    คำ ends in the nasal sound m and is a live syllable. Apply the live pattern with the consonant class and any tone mark. The absence of a separate written ม does not turn the sounded nasal into a stop ending.

The Nikhahit MarkLevel 6

Learn This First

The Nikhahit (นิคหิต) is a specialized orthographic mark used in Pali and Sanskrit loanwords. To understand it, you must first be comfortable with basic Thai script and vowel placement, as the mark appears above consonants and is the historical basis for the modern vowel 'am' (ำ). Familiarity with Pali/Sanskrit compounds (Samat) is also helpful as this is where the mark most frequently appears.
