definitive

"definitive" 的音标为 [dɪˈfɪnɪv] ，基本翻译为 "决定性的；最后的；确定的" 。

速记技巧：可以使用发音类似的词汇来帮助记忆，如 "de-fin-i-tive"，其中 "de-fin" 可以理解为 "定义" 的意思，而 "tive" 则表示形容词后缀，因此 "definitive" 可以理解为 "最终被定义的" 或 "决定性的"。

记忆方法：可以联想与 "define" 相关的词汇，如 "define" 可以理解为 "定义"，而 "definitive" 则可以理解为 "最终被定义的"，因此可以联想到 "最终的、确定的" 意思。同时，也可以将 "definitive" 与 "final" 进行比较，发现它们都有 "最终的" 意思，从而加深记忆。
