<注释>Although we do not know for certain the origin offad, first recorded in 834with the sense .whim, crotchet,.we can suggest one possibility.In 754, 80 years before this occurrence offad, we find an instance of the wordfidfad, meaning .a fussy person.:.The youngest . . . is, in everything she does, an absolute fidfad..Fidfad is found in the latter part of the 9th century with the sense .small detail, frill,. and the adjectivefidfad, meaning .frivolous, fussy, petty,. is recorded in 830.Fad could thus be a shortened form of fidfad, itself shortened from fiddle-faddle.
尽管我们不能确定fad 的起源， 它于834年首次被记录，用于表达.怪念头，异常态度或习惯.这一意思，我们仍可以提出一种可能。在754年，比fad 的出现早80年， 我们发现了一个词例fidfad， 表示.一个小题大作的人.：.这个年轻人…所做的一切事情都完全地小题大作。.在9世纪下半叶，fidfad 被发现有.小的细节，饰边.的意思， 而且形容词fidfad 还表示.无用的，大惊小怪的，不重要的.的意思， 于830年被记录。因此Fad 可能是 fiddle-faddle 被缩写为 fidfad 后的简便形式
