There are Thai words that sound almost exactly the same. The difference is sometimes the vowel; short vowel or long vowel, or the tone.
First pair of common words is ส้ม [sôm] = orange, and ส้อม [sôrm] = fork
The word orange is short vowel but the word fork is long vowel (it sounds a little longer than orange)
