It is true that the smallest unit of meaning found in a word is a
morpheme. Lower levels are only phonemes, which are letters, and they do
not have a specific meaning whatsoever, whereas morphemes do. For
example, re- in redo, means to do something again, or anti- in
antisocial means against society, opposite of society.
Explanation: morpheme .- a meaningful morphological unit of a language that cannot be further divided, e.g. come, in, if we add ing we can have the word incoming.
