specially (adv.)
13世纪晚期， specialli，“特别目的的，出于特殊原因的”，源自 special（形容词）+ -ly（2）。14世纪中期，“超过其他人，超越一切”。especially 的双重形式。
Special is more common than especial, which has the same meaning; but especially is for rhythmical reasons (because it occurs most frequently at the beginning of a dependent clause, where usually an unaccented particle occurs, and where, therefore, a word with an accent on the first syllable is instinctively avoided) much more common than specially. [Century Dictionary]
Special 比 especial 更常见，意思相同； 但是，由于韵律原因（因为它最常出现在从属从句的开头，通常会出现一个非重音粒子，在那里，因此，本能地避免使用一个重音在第一个音节上的单词）， especially 比 specially 更常见。[世纪词典]
