Exceptions with “ร” 
Today we will learn another rule to help you read and write Thai correctly.
Most of the time, when you see the consonant ท + ร, the cluster is pronounced as “s” sound, for example :
ทราย /saay/ = sand
ทรง /sohng/ = style
= a prefix for verbs and nouns to show royal use or connection to royalty
ทรัพย์/sáp/ = property, wealth
ทราบ /sâap/ = to know
ทรุดโทรม /sút-sohm/ = worn out, damaged, ruined
กระทรวง /grà-suang/ = ministry
Most of the time, when ศ, ส + ร, the cluster “ร” became silent, it is not pronounced at all ;
สร้อย /sôy/ = necklace
สระ /sà/ = to shampoo, to wash (hair)
ศรัทธา /sàt-taa/ = faith
ศักดิ์ศรี /sàk-sǐ/ = dignity
สร้าง /sâang/ = tocreate, produce, build
เสแสร้ง /sěh-sâeng/ = to pretend, fake, simulate
จริง**/jing/ = real, true
** จริงis the exception.
Enjoy Learning Thai ka, see you next time :)…
