Types of Thai Noodles เส้นก๋วยเตี๋ยว (if there is something wrong here, let me know at my firstname@domain
I needed to straighten noodle types in my head. Many of the words seem descended from Chinese and are hard to remember or pronounce.

• Gao Lao เกาเหลา is a noodle soup usually served with no noodles.
• Sen Lek เส้นเล็ก, with translates as little string shaped stuff
• Sen Yai เส้นใหญ่, see Sen Lek, but big
• Sen mii เส้นหมี่, this appears to be a rice noodle that is thin
• Guay Jab ก๋วยจั๊บ These are sheets of rice noodle.
• Khanom Jeen ขนมจีน . These are noodles made locally with a device that looks like a potato ricer. The rice flour is soaked for 3 days or so before being turned into noodles.
• Ba Mii บะหมี่, wheat with egg noogles
• Ba Mii  บะหมี่โคราช, Korat style ba mii noodles. I have no idea what makes them different.
• Giam Ee เกี้ยมอี๋ These are a thick short rice noodle with pointy ends. The Chinese names are quite colorful https://en.wikipedia.org/wiki/Silver_needle_noodles . I do not think that I have had them.
• Woon Sen วุ้นเส้น are made with mung bean flour
• Ma ma มาม่า , บะหมี่มาม่า or ramen is a brand name of ramen noodle but it is a word used generically for ramen.
• Gouitiow ก๋วยเตี๋ยว This seems to be a type of soup rather than a type of noodle. I find it tremendously hard to remember how to pronounce.
• Khao Soi, is a dish that is different in different places. But in Northern Thailand it usually has fried rice noodles. But the name is for the dish, not the noodle.
