The correct spelling of "wert applicable" should be "wert applicable" with the "wert" being an archaic spelling of "were." The word "applicable" means relevant or suitable, and it is pronounced /əˈplɪkəbl/ using the International Phonetic Alphabet. The sound /ə/ is an unstressed, schwa sound, followed by /ˈplɪ/ which is pronounced as a stressed syllable. The final sound of /kəbl/ is pronounced as two syllables, with the second syllable having a schwa sound.
The phrase wert applicable is not a commonly used term in English. Wert is an archaic form of the word were, which is the second person singular past tense of the verb to be in Old English. However, it is not clear what applicable means in this context since it is typically used independently, meaning capable of being applied or put into practice.
