Introduction to morphology

Morphology is concerned with the internal structure of words and the rules for forming words from their subparts, which are called morphemes.

Morphemes

1. Morphemes are the smallest units in the structural analysis of words.
2. [[[ green ] ish ] ness] [un [break [able]]]
3. It is often said that morphemes are the smallest units of meaning, but this is not quite accurate. They are the smallest structural units the learner identifies; to be identified as such a morpheme must have an identifiable grammatical behavior, but not necessarily an identifiable meaning. [ trans [ mit ]] [ trans [ miss ]] ion], [ per [ mit ]] [ per [ miss ]] ion], [ com [ mit ]] [ com [ miss ]] ion]
4. However, the root [mit] shows an identifiable contanst grammatical. Behavior: it changes to [miss] when the verb is used to make the corresponding noun through suffixation of [-ion]
