This document defines key terms in phonology. It explains that phonetics deals with the production of speech sounds without prior language knowledge, while phonology interprets phonetic patterns as part of a language's grammar. It defines allophones as contextual variants of the same phoneme. Various types of consonant sounds are defined, including approximants, fricatives, and plosives. Places of articulation for consonants are identified, such as bilabial, labiodental, interdental, alveolar, alveopalatal, velar, and glottal. Monophthongs are described as sounds produced with an open vocal tract.

1. GLOSARY (PHONOLOGY)
PHONETICS: the phonetics is the deals with the production of
speech sounds by humans, often without prior knowledge of the
language being spoken.
PHONOLOGY: the phonology as a grammar of phonetic and is a
interpretation of phonetic patterns, is about of sounds specially
different positions words.
ALLOPHONES:any of several sounds that are regardedas
contextual or environmental variants of the same phoneme.
VELUM:any of various veils-like bodily structures the soft palate.
APPROXIMANTS: are sounds made by narrowing the oral
cavity but not enough to cause turbulence in the airstream; the
airstream is said to be smooth.
FRICATIVES:it´s continuant consonant produced by partial
occlusion of the airstream.
PLOSIVES:Plosives consonant also known as a oral stop is a
consonant that is made by blocking a part of the mouth so that
air can pass through and the pressure increases behind the place
where it is a blocked.

2. MONOPHTHONGS:it’s a sound of the mouth tha is pronounce
with the vocal tract open.
PLACE OF ARTICULATION:we mean the area in the mouth at
which the consonantal closure or constriction occurs.
BILABIAL: sounds are made by bringing both lips together to
stop the air stream.
LABIODENTAL: sounds are made by bringing the top teeth into
contact with the bottom lip forcing air between the two to create
the fricatives.
INTERDENTAL:Sounds are made by placing the tip of the
tongue between the top and bottom teeth.
ALVEOLAR: Sounds are made by bringing the tongue and the
alveolar ridge.
ALVEOPALATAL: sounds are made by bringing the blade of the
tongue to our close to, the alveo-palatal is of the roof of the
mouth.
VELAR:Sounds are created by stopping the airstream by
bringing the back of the tongue into contact with the velum.
GLOTTAL: sounds are created by either narrowing the vocal
folds sufficiently to create a fricative or closing them to create a
stop.
