This character really makes my day! When I see 够 today and just find that its literal structure just helps to make sense of its meaning. Just look at this sentence: 够了，别说了！Enough, don’t say any more!
Actually, 够 is a semantic-phonetic character composed of the phonetic component 句 gōu and the semantic component 多. The original meaning of 句 is “bend.”. 勾 has two pronunciations jù and gōu. jù is for the meaning of “sentence” while gōu is for a surname such as the famous historical figure 勾践.
The original meaning of 够 was “The load-bearing planks of vehicles/wooden racks begin to bend because of the more-than-enough weight.
The original meaning of 够 was not changed much and all the present meanings are closely related to its original meaning. In modern Chinese, 多 has the following uses.
1. be enough, for example:
够标准 be up to standard
