The word "though" is pronounced with a voiced "th" sound followed by a long "o" sound, similar to "th-oh." Phonetically, it is /ðoʊ/ in American English and /ðəʊ/ in British English. Here's a breakdown of the pronunciation:

• The "th" is pronounced with the tongue between the teeth, producing a soft, voiced sound like in "this."
• The "ough" in "though" sounds like a long "o" vowel, as in the word "go."
  So, it sounds like "th-oh" with the emphasis on the "th" and the long "o" sound following it.
