Tenues (singular: tenuis ) are in linguistics (linguistics) the voiceless, not inspired or "hard" plosives, such as p, t, k
Examples from the Greek are the dental Tau, the labial and guttural Kappa Pi (t, p, k). Gutturals and labials change their clay form before a tenuis to a tenuis. Example: φ τ > πτ; ( Labial "ph " tenuis "t" > Tenuis "p " tenuis "t" ), so (written ) in γραπτός of γράφειν (write)
Other types of articulation, ie non- Tenues are, for example, the voiced mediae and breathy sounds ( Aspiratae ).
