can anyone tell me the difference between น้อยใจ and ใจน้อย ?

น้อยใจ = to feel hurt, to feel oneself to have been wronged

ใจน้อย = to be easily hurt or to be "touchy"

To add to that, I've often had trouble translating noy-jai. Have often encountered the translation, easily hurt by those close to you rather than the easily-hurt tag the dictionaries often give it.

Anyone got any thoughts on that?

I think something's mixed up here... As Mikenyork said, "noy-jai" means "hurt" (emotionally hurt, as in feeling slighted, ignored, or taken for granted), while "jai-noy" means "touchy" or "sensitive".

I agree with Mike and Peppy. Sample sentences from Lexitron:

หญิงที่ตั้งครรภ์มักจะใจน้อยง่ายกว่าปกติ

Pregnant women are more sensitive than they would normally be [if they were not pregnant.]

อมรน้อยใจเพื่อนๆ ที่ลืมวันเกิดของเขา

Amorn is peeved at her friends who forgot her birthday.

What do you think?

Can one make the generalization that 'XXX ใจ' denotes a temporary mood, while 'ใจ XXX' denotes a more permanent characteristic?

For example:

ดีใจ=glad, in a happy mood (for the time being)

ใจดี = of a happy disposition, character (generally)

Yes, I think as a rule of thumb that works in most cases.

Xใจ=temporary emotional state

ใจX=personality trait.
