Explain the essential difference between the notion phoneme and the notion morpheme

Not sure it seems quite difficult to me. You may want to email your teacher if nobody else replies

Answer: Morphemes are the smallest meaningful unit in a word which can stand alone (un/event/ful; cat/s). Phonemes are the smallest unit in language phonology - / b / or / m / (bat and mat are two different words, because of different phonemes). Phonemes are combined with other phonemes to form morphemes.

Explanation:

phoneme (/ˈfoʊniːm/) is a unit of sound that distinguishes 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,[1] the sound patterns / sɪn / (sin) and / sɪŋ / (sing) are two separate words that are distinguished by the substitution of one phoneme, / n/, for another phoneme, / ŋ/. Two words like this that differ in meaning through the contrast of a single phoneme form a minimal pair. If, in another language, any two sequences differing only by pronunciation of the final sounds [n] or [ŋ] are perceived as being the same in meaning, then these two sounds are interpreted as variants of a single phoneme in that language. while morpheme is the smallest meaningful unit in a language. A morpheme is not identical to a word. The main difference between them is that a morpheme sometimes does not stand alone, but a word, by definition, always stands alone. The linguistics field of study dedicated to morphemes is called morphology. When a morpheme stands by itself, it is considered as a root because it has a meaning of its own (such as the morpheme cat). When it depends on another morpheme to express an idea, it is an affix because it has a grammatical function (such as the - s in cats to indicate that it is plural).[1] Every word comprises one or more morphemes.
