When we look up a word on Google, it provides a nice dictionary which always contains a chart demonstrating Use over time.
Over time, an interesting fact has always occurred to me that the frequency of use of many words is declining. I found it really abnormal and somehow intriguing. Could you kindly point out what might be the reason and what it might indicate? Any possible answer would be welcome.
PS: I’m not sure whether this question is off-topic, if it is so, please leave a comment, and I will delete it. Thanks!
