The cause of synonyms

1. Although the generalized phenomena reflected in the meaning of several synonyms are consistent or basically identical, the emphasis and aspects may be different, and thus show subtle differences in the rational sense.

City: Inner City Guo: Outer City

Illness: General Illness: Serious illness ("Disease")

Leather: Furry hide Leather: Hairless hide

Hunger: Food shortage Bread: vegetable shortage

Friends: "Friends of the same teacher" Friends: "Comrades and friends"

2. Because words are used by people in communication, they are often permeated with people's subjective evaluation of the actual phenomena reflected in words, so people's subjective attitudes towards the same reality may be different, with praise and depreciation. as:

A B C

Old man, old man, old man

Old lady, old woman, old lady

Conduct

Attempts in vain

3. Different communication occasions require the use of words of different colors, or formal solemnity, or popular and casual. Therefore, in terms of the scope of its use, some words are mostly used in written language and solemn occasions, and some are mostly used in spoken language. For example, "father", "mother" and "father" and "mother", the former is mostly used in written language, and the latter is mostly used in spoken language. These can all give synonyms different additive colors. Another example is "birthday" and "birthday", "death", "death" and "death", "grief", "sadness" and "discomfort", these groups of words have different styles.
