Alveolar consonantAlveolar (ælˈviːələr; UK also ælviˈoʊlər) consonants are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli (the sockets) of the upper teeth. Alveolar consonants may be articulated with the tip of the tongue (the apical consonants), as in English, or with the flat of the tongue just above the tip (the "blade" of the tongue; called laminal consonants), as in French and Spanish. The International Phonetic Alphabet (IPA) does not have separate symbols for the alveolar consonants.
SibilantSibilants are fricative consonants of higher amplitude and pitch, made by directing a stream of air with the tongue towards the teeth. Examples of sibilants are the consonants at the beginning of the English words sip, zip, ship, and genre. The symbols in the International Phonetic Alphabet used to denote the sibilant sounds in these words are, respectively, [s] [z] [ʃ] [ʒ]. Sibilants have a characteristically intense sound, which accounts for their paralinguistic use in getting one's attention (e.g.
Velar consonantVelars are consonants articulated with the back part of the tongue (the dorsum) against the soft palate, the back part of the roof of the mouth (also known as the “velum”). Since the velar region of the roof of the mouth is relatively extensive and the movements of the dorsum are not very precise, velars easily undergo assimilation, shifting their articulation back or to the front depending on the quality of adjacent vowels.
Finnish languageFinnish (endonym: suomi ˈsuo̯mi or suomen kieli ˈsuo̯meŋ ˈkie̯li) is a Uralic language of the Finnic branch, spoken by the majority of the population in Finland and by ethnic Finns outside of Finland. Finnish is one of the two official languages of Finland (the other being Swedish). In Sweden, both Finnish and Meänkieli (which has significant mutual intelligibility with Finnish) are official minority languages. The Kven language, which like Meänkieli is mutually intelligible with Finnish, is spoken in the Norwegian county Troms og Finnmark by a minority group of Finnish descent.
SonorantIn phonetics and phonology, a sonorant or resonant is a speech sound that is produced with continuous, non-turbulent airflow in the vocal tract; these are the manners of articulation that are most often voiced in the world's languages. Vowels are sonorants, as are semivowels like [j] and [w], nasal consonants like [m] and [n], and liquid consonants like [l] and [r]. This set of sounds contrasts with the obstruents (stops, affricates and fricatives).
Apical consonantAn apical consonant is a phone (speech sound) produced by obstructing the air passage with the tip of the tongue (apex) in conjunction with upper articulators from lips to postalveolar, and possibly prepalatal. It contrasts with laminal consonants, which are produced by creating an obstruction with the blade of the tongue, just behind the tip. Sometimes apical is used exclusively for an articulation that involves only the tip of the tongue and apicolaminal for an articulation that involves both the tip and the blade of the tongue.
Place of articulationIn articulatory phonetics, the place of articulation (also point of articulation) of a consonant is a location along the vocal tract where its production occurs. It is a point where a constriction is made between an active and a passive articulator. Active articulators are organs capable of voluntary movement which create the constriction, while passive articulators are so called because they are normally fixed and are the parts with which an active articulator makes contact.
Liquid consonantIn phonology, liquids are a class of consonants consisting of voiced lateral approximants like /l/ together with rhotics like /r/. The grammarian Dionysius Thrax used the Ancient Greek word ὑγρός (, ) to describe the sonorant consonants (/l, r, m, n/) of classical Greek. Most commentators assume that this referred to their "slippery" effect on meter in classical Greek verse when they occur as the second member of a consonant cluster. This word was calqued into Latin as liquidus, whence it has been retained in the Western European phonetic tradition.
Distinctive featureIn linguistics, a distinctive feature is the most basic unit of phonological structure that distinguishes one sound from another within a language. For example, the feature [voice] distinguishes the two bilabial plosives: [p] and [b]. There are many different ways of defining and arranging features into feature systems: some deal with only one language while others are developed to apply to all languages. Distinctive features are grouped into categories according to the natural classes of segments they describe: major class features, laryngeal features, manner features, and place features.
Secondary articulationIn phonetics, secondary articulation occurs when the articulation of a consonant is equivalent to the combined articulations of two or three simpler consonants, at least one of which is an approximant. The secondary articulation of such co-articulated consonants is the approximant-like articulation. It "colors" the primary articulation rather than obscuring it. Maledo (2011) defines secondary articulation as the superimposition of lesser stricture upon a primary articulation.
