- Linguistics : The scientific study of language.
- Language (linguistics) : A type of communication system, commonly used in linguistics, computer science and other fields to refer to different systems, including 'natural language' in humans, programming languages run on computers, and so on. A wider definition of language - what counts as a language and what doesn't - is a difficult philosophical topic, deserving an article in its own right.

- Syllable : Unit of organisation in phonology that divides speech sounds or sign language movements into groups to which phonological rules may apply.
- Phoneme : Theoretical unit of language that can distinguish words or syllables, such as /b/ versus /m/; often considered the smallest unit of language, but is a transcription convention rather than a true unit in most models of phonology since the 1960s.
- Vowel : Speech sound with relatively unhindered airflow; different vowels are articulated mainly through tongue movements at the palatal and velar regions of the mouth, and are usually voiced (i.e. involve vocal fold movement).
- Consonant : Unit of language, defined in phonetics as a speech sound that involves full or partial 'closure' of the mouth, and in phonology as a segment that cannot occupy the nucleus or 'peak' of a syllable.
- Voicing (linguistics) : Either the physical production of vibration by the vocal folds as part of articulation, or the potential phonological distinction this allows, i.e. the distinct difference between units such as [b] and [p] in many languages.
