أرجع لكلام الباحثة الذي جلبته وكأنه صيد ثمين أكثره مطروق نسميها fronting بعض من هذا ال fronting يكون فيه inversion وبعض أخر دون ذلك و أستخدامه خصوصا في ال spoken language أو في اغاني الأطفال rhyming وأحيانا لغرض التوكيد سأضرب مائة مثال أو ألف أما جملتك ( most concerned was she ) مع هكذا تركيب مستحيل ومع أنني متأكد ومن أول تعليق لي , ومع ذلك ذهبت وطرحت السؤال في أحد المنتديات الأجنبية كما في الصورة
( لأنه أنت لا تقنع ومتمسك برأيك وحتى لو تعرف خطأ ربما تتصور أنها مهارة أو تأخذك العزة بالأثم ولا تعترف بخطأ ) !!
وأصلا جملتك كلها غلط ( الترجمة غلط ) ليس هكذا يترجم البيت الشعري ( راعها منهُ صَمتُهُ و وجُومُهُ وشَجاها شُحُوبُهُ وسُهومُهْ )

Simply I can translate as :
What made her so scared \ frightened of him, is his silence
And you can complete with the second verse of yours
Moreover, she was too saddened over his palling , puzzling face
And if you ask about the rhyme ; I see it is nearly equal
Use ( ing -adjective ) not ed-adjective = something affects on the hearer or the watcher (comes external )
عندما تكون أنت نفسك من هو متأثر استخدم صفات ed -participle
أما مصدر التأثير على الطرف الأخر فتكون الصفات معه ing -participle

لا أحد يعقلها في أي مكان عبارتك

Is it right or wrong to say "Most concerned was she "

Hello.
Your example-most concerned was she-sounds very awkward and I would never use it. You sometimes see unusual word order in songs for rhyming. In conversation, people give prominence to a word by stressing it. Moving something to the beginning or front of a sentence is a technique to indicate what the speaker thinks is most important, but it can make odd sentences that native speakers tend to avoid.
