Over the generations, humans invented a very large store of labels for individuals and categories of things in the world (even categories of things not in the world)
Reasons for lexical differentiation
Differences in environment, culture, and specific interest or experience
Environment
Tribes in different parts of the world with no contact with each other, each experiencing a different environment containing its own potentially unique set of animals and plants, climate and geology
Environmental differences
Amharic has a word for hippopotamus, Inuktitut does not
Culture
Cultures of different tribes differ, resulting in differences in their store of words
Cultural differences leading to lexical differentiation
1. Certain naturally occurring things become more important
2. Development of cultural artifacts
3. Development of abstractions and concepts that do not represent physical things
Specialization
As culture progresses, experts emerge who invent words not known to everyone in the tribe
Modern languages like Mandarin Chinese, English, Spanish, and Japanese have more words than Amharic, Tzeltal, Lingala, and Inuktitut
There is no evidence that individual speakers of English or Japanese know any more words than individual speakers of Amharic or Tzeltal
Ways new words are created in a language
1. Semantic extension of an existing word
2. Creating a new word out of combinations of old words or pieces of old words
3. Borrowing the word from another language

Kinship terms

Differences in kinship terms are more likely to be related to culture than differences in personal pronouns
Children growing up in a particular culture are learning the cultural concepts and the words simultaneously
