The spelling of "wert relevant to" may seem unusual at first glance, but it is actually a contraction of the archaic subjunctive form "were it relevant to." The pronunciation of "wert" is /wɜːt/, with the "e" pronounced as the "e" in "her" and the "r" pronounced in a slightly rolled manner. The word "relevant" is pronounced /ˈrɛləvənt/, with the stress on the second syllable and the "a" pronounced as the "a" in "cat." Overall, "wert relevant to" is a formal and rarely-used phrase in modern English.
