“这个人蛮好的”常见的英文表述有:“This person is quite nice.” 或者 “This person is very good.”
“quite” 有“相当,很”的意思,“nice”侧重于形容人“友好的,令人愉快的,和蔼的”。所以 “This person is quite nice.” 能表达出“这个人蛮好的”。
“very” 表示“非常”,“good” 有“好的,优秀的,善良的”等含义。“This person is very good.” 也可以准确传达“这个人蛮好的”这种意思。
例如:I met him yesterday and found this person is quite nice.(我昨天见到他了,发现这个人蛮好的。) 或者 Everyone says this person is very good. (大家都说这个人蛮好的。)
