Many a 用于句首引起倒装,请问是如何倒装呢?能给个句子吗?

Many a time has the manager emphasized this point.经理多次强调这一点
正常语序：the manager has emphasized this point many a time.has 与manager 倒装,但这属于部分倒装,因为has在此是助动词.这个倒装是因为many a time 在句中充当了状语,且提前至句首才引起倒装的.(注：many a +...要构成状语,例句中是频率状语）
所以值得注意的是：many a +名词,并不都倒装.如 many a man has gone to the big cities for work.这句话是正常语序,没有倒装,many a man 做句子的主语.
