Common Thai Grammar Mistakes to Avoid
Gender Agreement Errors
In Thai, verbs and adjectives must agree with the gender of the noun. This is one of the most common mistakes — our checker catches these automatically.
Incorrect Postpositions
Using the wrong postposition (like "में" vs "पर" in Hindi, or equivalent markers in Thai) changes the meaning of a sentence. Our tool identifies these errors.
Spelling and Matra Errors
Small mistakes in vowel marks (matras) or similar-looking characters can change a word's meaning entirely. The spell check catches these subtle errors.
Redundant Words
Repeating the same concept with different words (like saying "return back") is common in Thai writing. Our style checker flags unnecessary redundancies.

Thai Script
Thai script has 44 consonants, 15 vowel symbols, and 4 tone marks. Words are written continuously without spaces — spaces appear only between sentences or clauses.
Writing Challenges
Thai is a tonal language with 5 tones, and written Thai has no spaces between words, making word segmentation a key challenge for grammar and spell checking.
