Correct usage with commas and conjunctions [duplicate]

Solution 1:

"Though" is an interchangeable conjunction with "even though" and "although", and even though it sounds weird to some, the first usage (1.) is correct, while the usage with the semi-colon is debatable.

Examples 3 and 4 are both correct. In 3, you have the appositive set off by commas, either because of a pause or because of its lack of restrictiveness, or both. However, I would recommend putting commas around "Sarah" in the second example, as it can be a non-restrictive appositive also. Some may say that the lacking of commas prompts one to think that there are multiple wives in context. That might be reaching, so let's just say that the pause sounds better; "Jame's stunning wife, Sarah, walked down the aisle on the wedding day." This is purely a suggestion.
