Hello Tim,

Thank you very much for your comment and questions.

การศึกษา (n) Education gaan sùek-sǎa

***because ศึกษา sùek-sǎa is an action verb, so it goes with prefix การ

ความเคารพ (n) Respect khwaam khao-róp ***เคารพ khao-róp is a "abstract ideas" so it goes with prefix ความ

like ความฝัน dream

I think you confuse between the two ความอบอุ่น (n) khwaam-òp-ùn warmth and ครอบครัว (n) khrâawp-khruua family but ของเล่น (n) khǎawng-lên is toy which is the word underneath "warmth".

There are lesson provided special for the two prefix above, but memorized or use dictionary to help you which one to used will be best option. Hope that's help. Please do not hesitate to ask if you have future questions. I will be glad to help. We wish you will have a good progress with Thai. 😄

Wish you a great day.

ps I noticed that on other page you write the word khwaam differently.

ของเล่น (n)

khǎawng-lên

Why is it that both of these words are nouns, but one has gaan and other khwaam in front of it?

gaan sùek-sǎa
