สงสัย ? From a dictionary : สงสัย sohngR saiR to doubt; suspect; wonder about . If I say: I wonder what time he would be back, it would be ,maybe : Pom sohng sai waa kao ja glap maa meuaa rai? But, If I say : I doubt he will come back , it would be, Pom sohng sai waa kao ja mai glap maa All the above correct in their meanings ? Furthermore , how about the sentences , I doubt he is the thieve (meaning I dont think he is) and 'I suspect he is the thief ( meaning I think he is) ,wouldnt the usage of sohng sai as defined by the dictionay distort my meanings. Thank You
