請問在戰鬥中，VS的長寫是什麼？同埋點解？

vs 亦可以寫成 v，全寫是 versus，要注意：versus 不一定解 「對戰」，還有其他意思，詳情請參考以下資料：

v (AGAINST) (preposition) (ALSO vs)
1 ABBREVIATION FOR versus:
e.g. I need to consider the advantages v the disadvantages.

2 used to show who is competing in a game:
e.g. Sunderland United v Worthing

3 used to show the two sides involved in a court case:
e.g. the 1973 Supreme Court decision, Roe v Wade

vs (preposition)
WRITTEN ABBREVIATION FOR versus

versus (preposition)
1 (WRITTEN ABBREVIATION v or vs) used to say that one team or person is competing against another:
e.g. Tomorrow's game is Newcastle versus Arsenal.

2 (WRITTEN ABBREVIATION v or vs) used in legal cases to show who a person is fighting against:
e.g. Abortion was legalized nationally in the United States following the Roe versus Wade case.

3 used to compare two things or ideas, especially when you have to choose between them:
e.g. private education versus state education

VS 長寫係 versus
其實正確係 vs. 你知道之後就算係yahoo字典都會搵到。
