<注释>The wordgiddy refers to fairly lightweight experiences or situations, but at one time it had to do with profundities.Giddy can be traced back to the same Germanic root .gud- that has given us the wordGod. The Germanic word.gudigaz formed on this root meant .possessed by a god.. Such possession can be a rather unbalancing experience,and so it is not surprising that the Old English representative of.gudigaz, gidig, meant .mad, possessed by an evil spirit,. or that the Middle English development ofgidig, gidi, meant the same thing, as well as .foolish; mad (used of an animal); dizzy; uncertain, unstable..Our sense .lighthearted, frivolous,. represents the ultimate secularization ofgiddy.
单词giddy 完全是指不必要的经历或情况， 但同时与深度有关。Giddy 能被追溯到它的德语词根 gud- ， 从同一词根我们得到单词God 。 德语词gudigaz 由这个词根形成的意思是.由上帝占有.。 这种拥有可以是一种不平衡的经历，所以对于gudigaz ,gidig 在古英语的表达并不奇怪， 意思是.疯狂的，被恶魔占据的.或gidig, gidi 有在中古英语中发展而来的同样的意思， 另外还有.呆的；疯狂的（用于动物）；头晕眼花的；不确定的，不稳定的。.我们.轻浮的，轻佻的.的解释代表了最终世俗化的giddy
