The smallest sounds of language are known as phonemes. They are the smallest units of sound in speech that can distinguish one word from another. For example, in the words 'bat' and 'pat', the change from /b/ to /p/ alters the meaning. Phonemes do not carry meaning in themselves but are fundamental in the construction of words. All languages contain phonemes, and all spoken languages include both consonant and vowel phonemes.

Phonemes are the smallest unit of sound in a language
Phonemes are the smallest units of sound that exist in a language. They are sets of similar speech sounds that are perceived by native speakers as a single basic sound. These sounds help to distinguish one word from another, such as the difference between the words "bat" and "pat", where the change from /b/ to /p/ alters the word's meaning.
Phonemes are studied under phonology, a branch of linguistics. They are often represented in writing by a glyph enclosed within two forward-sloping slashes. For example, the sound at the beginning of the word "cat" can be represented as /k/. This is distinct from the sound /b/ at the beginning of the word "bat".
In some languages, word stress can also be phonemic. For example, in English, the word "invite" can be either a verb or a noun. The difference in meaning is indicated by the position of the stress: /ɪnˈvaɪt/ for the verb, and /ˈɪnvaɪt/ for the noun.
The smallest unit of meaning in a language is called a morpheme. For example, the word "cats" indicates that there is more than one cat, so "cat" is a morpheme. Morphemes can be either a whole word or a part of a word that carries meaning, like a prefix. Phonemes, on the other hand, do not carry meaning by themselves but are fundamental in the construction of words.

Morphemes are the smallest unit of meaning in a language
Morphemes are the smallest meaningful units in the structure of a language. They are the smallest constituents within a linguistic expression that can carry meaning. For example, the word “in” has meaning, and no smaller segment of it has meaning, so it is a morpheme. Similarly, “un” is a morpheme in "unintelligible", meaning "not" as in "not intelligible".
Some words, such as “formatives” or “interfixes”, are sometimes referred to as morphemes but do not usually have meaning. Morphemes can be standalone words, while other words contain multiple morphemes. The main morpheme in a word with multiple morphemes gives the word its basic meaning and is called the root. For example, “cat” is the root morpheme in the word “cats”. Additional bound morphemes, called affixes, may be added before or after the root, such as the "-s" in "cats", which indicates plurality.
The field of linguistics dedicated to morphemes is called morphology. Morphological analysis is the process of segmenting a sentence into a row of morphemes, and it is closely related to part-of-speech tagging. This type of analysis is used in natural language processing for Japanese, Chinese, and other languages where word boundaries are not indicated by blank spaces. The purpose of morphological analysis is to determine the minimal units of meaning in a language (morphemes) by comparing similar forms.
It is important to note that phonemes are different from morphemes. Phonemes are the smallest unit in the sound system of a language that has meaning when combined together. They are sets of similar speech sounds that are perceived by speakers of a language as a single basic sound. For example, the sound /k/ is the phoneme at the beginning of the word "cat". Phonemes are studied under phonology, a branch of linguistics.

Phones are the smallest distinguishable unit of a speech sound
Phones are the smallest distinguishable units of speech sound. They are the smallest perceptually distinguishable segments of sound in a stream of speech. For example, the /c/ sound in "the cat meowed" is a phone.
Phones are distinguished by native speakers of a given language, who perceive them as a single basic sound. For instance, in English, the sounds [n] and [ŋ] are separate phonemes as they distinguish words like "sin" and "sing". However, in other languages such as Spanish, these sounds comprise a single phoneme.
The concept of a phoneme was initially developed to understand patterns of organisation among the diversity of phones heard in languages. Phonemes are the smallest sound units of language whose presence, absence, or substitution can distinguish between words. For example, the sounds /p/ and /b/ are considered phonemes as they distinguish between words like "pat" and "bat".
Phonemes are not universal across languages. They are studied under phonology, a branch of linguistics encompassing language, writing, speech, and related matters. Phonemes are often represented in writing by a glyph enclosed within two forward-sloping slashes. For example, /k/ represents the phoneme at the beginning of the word "cat".
While phones are the smallest distinguishable units of speech sound, phonemes are the smallest units of sound that can change word meaning in a language.

Syllables are the smallest rhythmic unit of language
While phonemes are the smallest units of sound, we don't actually speak in phonemes. For instance, if you say the word "cat" /kæt/ and record it, you won't be able to break it into three units of /k/, /æ/, and /t/. Hence, the smallest unit of articulation is not the phoneme but the syllable.
A syllable is a basic unit of organization within a sequence of speech sounds, such as within a word. It is typically defined by linguists as a nucleus (most often a vowel) with optional sounds before or after that nucleus (margins, which are most often consonants). In phonology and language studies, syllables are often considered the "building blocks" of words. They can influence the rhythm of a language: its prosody or poetic meter.
The term rime covers the nucleus plus coda. In the one-syllable English word "cat," the nucleus is a (the sound that can be shouted or sung on its own), the onset c, the coda t, and the rime at. This syllable can be abstracted as a consonant-vowel-consonant syllable, abbreviated CVC. Languages vary greatly in the restrictions on the sounds making up the onset, nucleus, and coda of a syllable.
Syllables are the smallest units of articulation and provide the rhythmic patterns of a language. In languages such as English, syllables carry features such as stress. This determines which syllable in a word receives emphasis. For example, in the phrase "I am recording a song," the second syllable in the word "recording" is stressed. Now, say "That was a record." You will find yourself placing more stress on the first syllable of the word "record." Languages that place equal time periods for stressed syllables are called stress-timed languages. English is a stress-timed language, and we can see how this is employed in Shakespeare's sonnets with iambic pentameters. Each line consists of five iambs, and each iamb consists of two syllables, with the second being more stressed than the first.

Syntax is the system of rules that govern how words can be arranged to form phrases and sentences
Syntax is a set of rules that govern how words are combined to form grammatically correct sentences. It involves word order, phrase structure, and the construction of different types of sentences. Syntax is an essential component of grammar and helps us to construct meaningful and well-organized sentences.
The word "syntax" comes from the Ancient Greek word "syntaktikos," which means "to put in order" or "to arrange." Syntax is an important concept in linguistics, the scientific study of language. It is concerned with the way words are arranged to form sentences, focusing on the structure and rules of sentence formation.
Syntax is crucial for effective communication and understanding the nuances of language. For example, in the sentence "The boy kicked the ball," the typical Subject-Verb-Object order is followed. Changing the word order to "The ball kicked the boy" completely alters the meaning, demonstrating the importance of syntax in conveying the intended message.
Syntax also involves the study of relationships among similar sentences. For instance, the sentences "John saw Mary" and "Mary was seen by John" have similar structures but differ in word order, resulting in different interpretations.
At a fundamental level, syntax deals with the arrangement of words and phrases to create meaningful sentences. This includes the specific order in which words and phrases are placed, as small changes in word order can dramatically influence the interpretation of a sentence. For example, "she only loves pizza" and "only she loves pizza" use the same words but convey different meanings due to the difference in word order.
Syntax is a complex system of rules that allows us to organize words into sentences, conveying our intended messages clearly and effectively. It is an essential aspect of language, enabling us to communicate and understand each other.

Frequently asked questions
The smallest sounds of language are called phonemes.
Phonemes are the smallest unit of sound in speech that can distinguish one word from another. For example, in the words 'bat' and 'pat', the change from /b/ to /p/ alters the meaning.
Phonemes are often represented, when written, as a glyph (a character) enclosed within two forward-sloping slashes /. So, for example, /k/ represents the phoneme or sound used in the beginning of the English language word cat.
Morphemes are the smallest units of meaning in a language. Phonemes, on the other hand, are the smallest sound units. For example, the word 'cat' is a single free morpheme as it stands alone and conveys meaning.
