この話の内容がいまいち理解できません😔 どなたか詳しく教えて頂けると助かります!!!!!!!!!💧 宜しくお願いします!!!!!!!🙇🏽‍♀️🙇🏽‍♀️

0 The English language is full of words which have changed their meanings 3lightly or even dranmatically over the centuries. Changes of meaning can be of a number of I (of の用法)【nice の意味の変遷) different types. Some words, such as nice, have changed gradually. Emotive words tend 例示1企 今例示2 2(文構造) to change more rapidly by losing some of their force, so that awful, which originally とzthe meant ‘inspiring awe', now means Very bad’ or, in expressions such as awfully good, い 5 simply something like *very. In any case, all connection with ‘awe' has been lost. 2 Some changes of meaning, though, seem to attract more attention than others. (0This is perhaps particularly the case where the people who worry about such things 3 (the case where 】 【文構造】 believe that a distinction is being lost. For example, there is a lot of concern at the moment about the words uninterested and disinterested. In modern English, the positive 10 form interested has two different meanings.

(2)It is not a problem that this word has more than one meaning. Confusion never 小理由 seems to occur, largely because the context will normally make it obvious which meaning is intended. In all human languages there are very many words which have more than one meaning- this is a very common and entirely normal (3)state of affairs. Most 20 English speakers, for example, can instantly think of a number of different meanings for the words common and state and affairs which I have just used.
