我想在WP中翻译一个单词，但我不想替换整个翻译文件（.mo和.po），因为只有一个单词（它将被下一个WP版本覆盖，我必须经常记住）。

是否可以只翻译一个单词而不覆盖其余的单词？

P、 S.：我需要在/wp includes/script loader中将“no subset”翻译成“西里尔文”。php：

            /* translators: To add an additional Open Sans character subset specific to your language,
             * translate this to \'greek\', \'cyrillic\' or \'vietnamese\'. Do not translate into your own language.
             */
            $subset = _x( \'no-subset\', \'Open Sans font: add new subset (greek, cyrillic, vietnamese)\' );

            if ( \'cyrillic\' == $subset ) {
                    $subsets .= \',cyrillic,cyrillic-ext\';
            } elseif ( \'greek\' == $subset ) {
                    $subsets .= \',greek,greek-ext\';
            } elseif ( \'vietnamese\' == $subset ) {
                    $subsets .= \',vietnamese\';
            }

            // Hotlink Open Sans, for now
            $open_sans_font_url = "//fonts.googleapis.com/css?family=Open+Sans:300italic,400italic,600italic,300,400,600&subset=$subsets";
    }
