Key Differences
In the realm of linguistics, morpheme and phoneme are foundational concepts. A morpheme is essentially the smallest unit of a language that holds meaning. For instance, the word "unhappiness" consists of three morphemes: "un-", "happy", and "-ness". Phoneme, on the other hand, pertains to the domain of sounds. It is the smallest unit of sound that can distinguish one word from another. For example, the difference in the initial sounds of "pat" and "bat" is a result of the phonemes /p/ and /b/ respectively.
When analyzing language, understanding the distinction between morpheme and phoneme is crucial. Morphemes can be words themselves, or they can be parts of words, like prefixes or suffixes. These units provide the foundation upon which words are built and convey specific meanings. Phonemes, however, do not have inherent meaning. They function to differentiate words but aren't tied to specific semantic content.
The relationship between morpheme and phoneme becomes clearer when considering how languages evolve. Morphemes shift in response to cultural or contextual changes that necessitate new meanings. Phonemes, conversely, might change as accents evolve or as languages come into contact with one another. The shifts in phonemes don't inherently change the meaning of the words, but they can influence pronunciation.
In summary, while both morphemes and phonemes are elemental units in linguistics, they operate in different capacities. Morphemes are the building blocks of meaning, and phonemes are the building blocks of sound. Both play essential roles in shaping the complexities and nuances of human language.

Morpheme
Not always a word, but always carries meaning.
-ed is a morpheme indicating past tense.
Phoneme
Abstract representation of speech sounds.
/t/ and /d/ are distinct phonemes in English.
Morpheme
Smallest unit of meaning in a language.
The word dogs has two morphemes: dog and -s.
Phoneme
Can change word meaning if substituted.
Changing the phoneme /m/ to /n/ in mat results in nat.
Morpheme
Can be a prefix, root, or suffix.
In unhappiness, un- is a morpheme.
Phoneme
Not related to alphabetic letters.
The word shoe starts with the phoneme /ʃ/.
Morpheme
Can be free or bound.
Book is a free morpheme, while -ing is a bound morpheme.
Phoneme
Smallest sound unit that can differentiate meaning.
The phoneme /r/ distinguishes rat from bat.
Morpheme
Constituent parts that create complex words.
Unbelievable consists of three morphemes: un-, believe, and -able.
Phoneme
In phonology and linguistics, a phoneme is a unit of sound that can distinguish one word from another in a particular language. For example, in most dialects of English, with the notable exception of the West Midlands and the north-west of England, the sound patterns (sin) and (sing) are two separate words that are distinguished by the substitution of one phoneme, /n/, for another phoneme, /ŋ/.
Morpheme
A morpheme is the smallest meaningful lexical item in a language. A morpheme is not necessarily the same as a word.
Phoneme
Any of the perceptually distinct units of sound in a specified language that distinguish one word from another, for example p, b, d, and t in the English words pad, pat, bad, and bat.
Morpheme
A meaningful linguistic unit that cannot be divided into smaller meaningful parts. The word man and the suffix -ed (as in walked) are morphemes.
Phoneme
The smallest phonetic unit in a language that is capable of conveying a distinction in meaning, as the m of mat and the b of bat in English.
Morpheme
(linguistic morphology) The smallest linguistic unit within a word that can carry a meaning.
Phoneme
An indivisible unit of sound in a given language. A phoneme is an abstraction of the physical speech sounds (phones) and may encompass several different phones.
Morpheme
The smallest unit of meaning of a language, which cannot be divided into smaller parts carrying meaning; it is usually smaller than a single wordform, such as the -ed morpheme of verbs in the past tense or the -s morpheme of nouns in the plural form.
Phoneme
(linguistics) one of a small set of speech sounds that are distinguished by the speakers of a particular language
Morpheme
Minimal meaningful language unit; it cannot be divided into smaller meaningful units
Phoneme
Fundamental to the pronunciation of words.
The word thin contains the phoneme /θ/.
