Please teach me the difference between words, morphemes and morphemes

I am studying Chinese language, morphemes form words, words form phrases, phrases form sentences. Basically this is the hierarchical deconstructive relationship, it seems that the reference to the lexeme is relatively rare, and now most of them are divided by morphemes, right, do not know much about the lexeme.

Nowadays, analyzing words is mainly based on morphemes rather than lexemes.

There are three main methods: substitution, residual, and phonological.

For example, bird's-eye view is composed of two morphemes: "bird" and "view". "Bird's eye view" can be composed of "overlooking" and "bird" can be composed of "bird shit". Note that the original position cannot be changed, and that after substitution, the morpheme will have the same meaning in the new word as in the original word.

"Butterfly", initially in the ancient Chinese language can not be split into practical, see a morpheme composition of the word, in modern Chinese, "butterfly" is gradually used alone, such as "Butterfly Loves Flower". In modern Chinese, "蝴" is gradually used alone, as in "蝶恋花", so "蝴" is also a morpheme judged by the residual method.

I hope this is useful to you
