“wot” is pronounced as /wɒt/. It rhymes with “hot” but with a “w” sound at the beginning. The “o” is pronounced like the “o” in “hot”.
“t” is simply pronounced as /tiː/ when it is the letter by itself. However, when “t” appears in words, its pronunciation can vary depending on its position and the surrounding letters. For example, in “top”, it is a sharp /t/ sound. In “butter”, it is a softer sound due to assimilation.
