adverb
Only when written 強勢
Archaic adverbial use, restricted to the kanji form 強勢. Not used in modern Japanese.
古文書では「強勢に」と書いて「ごうせいに」と読ませる例がある。
In old documents, there are examples where 強勢に is written and read as ごうせいに.
The kanji 豪 means 'powerful' or 'magnificent', and 勢 means 'force' or 'vigor'. Together they suggest overwhelming scale or splendor. The reading ごうせい is standard; こうせい is an obsolete reading for 強勢.
