"PRAISUK" is a non-standard spelling of the word "pricey" which means expensive. The correct spelling of the word is pronounced /ˈpraɪsi/, with the stress on the first syllable. The "y" at the end of the word represents the sound /i/, as in the word "ski". The mispelling of the word is likely due to phonetic confusion, as the sound /aɪ/ in "price" is similar to the sound /aʊ/ in the word "house".
