A lymphocyte is a type of white blood cell (leukocyte) in the immune system of most vertebrates. [1] Lymphocytes include T cells (for cell-mediated and cytotoxic adaptive immunity), B cells (for humoral, antibody-driven adaptive immunity), [2] [3] and innate lymphoid cells (ILCs; "innate T cell-like" cells involved in mucosal immunity and homeostasis), of which natural killer cells are an ...
The charts below show the way in which the International Phonetic Alphabet (IPA) represents Igbo language pronunciations in Wikipedia articles. This reflects Standard Igbo, and dialects may have more or fewer phonemes.
Pronunciation can change over time. Dictionaries may list the most commonly used forms of words, but as language changes, dictionaries change as well. At best, any guide to suggested pronunciation can reflect the preponderance of usage.
The following are the non-pulmonic consonants.They are sounds whose airflow is not dependent on the lungs. These include clicks (found in the Khoisan languages and some neighboring Bantu languages of Africa), implosives (found in languages such as Sindhi, Hausa, Swahili and Vietnamese), and ejectives (found in many Amerindian and Caucasian languages).
The official summary chart of the IPA, revised in 2020 The International Phonetic Alphabet ( IPA ) is an alphabetic system of phonetic notation based primarily on the Latin script . It was devised by the International Phonetic Association in the late 19th century as a standard written representation for the sounds of speech . [ 1 ]
Within the chart “close”, “open”, “mid”, “front”, “central”, and “back” refer to the placement of the sound within the mouth. [3] At points where two sounds share an intersection, the left is unrounded, and the right is rounded which refers to the shape of the lips while making the sound. [4]
The following is the chart of the International Phonetic Alphabet, a standardized system of phonetic symbols devised and maintained by the International Phonetic Association. It is not a complete list of all possible speech sounds in the world's languages, only those about which stand-alone articles exist in this encyclopedia.
