How to understand 美人只配强者拥有? I know its meaning. But I can't understand it in grammar.
And does that means when it becomes an adage or 梗, we don't need to care about the grammar?
&quot;美人只配(被)强者拥有&quot; is  a [(topic) + (comment/ opinion)] sentence.
(this phrase diminish the value of beauties)

It is not an adage

Topic: 美人 (beautiful women)

Comment: 只配被强者拥有 (only worthy of being owned by the strong ones)


美人 (beautiful women)
只配 (only worthy of)
被(by) omitted
强者(the strong one)
拥有 (to own)
The sentence above means &quot;Beautiful women only deserve to be owned by the strong ones&quot;
Substitute the topic and comment:

木棒只配給材民作武器
Topic: 木棒 (Wooden stick)
Comment: 只配給村民作武器 (only worthy of used as weapon by villagers)

~

聖劍只有英雄才配揮舞
Topic: :聖劍 (Holy sword)
Comment: 只有英雄才配揮舞 (only hero deserve to swing it)

&quot;美人只配(被)强者拥有&quot; is different from &quot;只有强者才配拥有美人&quot; (only the strong ones deserve to own beautiful women). Which is a [SVO] sentence

只有强者才配拥有美人 (only the strong ones deserve  to own beautiful women)
(this phrase elevate the status of the strong ones)

[S] = 强者 (the strong ones)
[V] = 拥有 (own)
[O] = 美人 (beautiful women)
只有 ~ 才 ~ is a conjunction  (only)
配 (worthy of) is an adverb for the verb 拥有 (own)
