Words Starting With "A"

Our pre-recorded sounds are fast, clear, and natural, spoken by native speakers.

Aphthong

speak

An "aphthong" is an archaic term used in phonetics and linguistics to refer to a vowel sound that is not a pure vowel, but instead has some degree of glide or movement towards another vowel sound. It is also known as a "vowel harmony" or "glide." The term is not commonly used in modern linguistic studies, and its usage varies across different historical contexts and languages.

Aphthongal

speak

Aphthongal refers to something related to or involving aphthongs, which are vowel sounds that are pronounced without any significant change in the position of the tongue or lips throughout their duration. It can also pertain to the study or classification of such sounds in linguistics.

Aphthongs

speak

Aphthongs are vowels that are pronounced without any significant change in the position of the tongue or lips throughout their duration. They are also known as "pure vowels" or "monophthongs." Examples include the "ah" sound in "father" or the "ee" sound in "beet."

Aphthous

speak

Aphthous refers to a type of mouth ulcer, commonly known as a canker sore. These are small, painful sores that can appear on the inside of the lips, cheeks, tongue, or gums. They are not contagious and usually heal on their own within a few weeks. The exact cause is not always clear, but they may be triggered by stress, injury, certain foods, or vitamin deficiencies.

Aphylla

speak

Aphylla means "without leaves" or "leafless" in Greek. It is often used to describe plants that have few or no visible leaves, or to refer to plant parts that lack foliage.

Aphyllanthaceae

speak

Aphyllanthaceae is a family of flowering plants in the order Malpighiales. It consists of shrubs, trees, and herbaceous plants, commonly known as the leafless or spineless family due to some species having reduced or no leaves. The family includes around 70 genera and about 1,200 species, with a widespread distribution in tropical and subtropical regions. Notable genera within Aphyllanthaceae include Euphorbia (which includes the spurge plants) and Phyllanthus (which has medicinal and ornamental species).

Aphyllanthes

speak

Aphyllanthes is a genus of plants in the family Asteraceae. It consists of species commonly known as "leafless" or "scale-leaved" plants, due to their reduced or absent foliage. These plants have adapted to arid or semi-arid conditions, conserving water by minimizing leaf surface area.

Aphyllophorales

speak

Aphyllophorales is an order of fungi commonly known as the "gilled mushrooms" or "pored mushrooms." These fungi produce spores on gills or pores underside their caps, rather than having gills openly exposed (hence the prefix "a-phylllo," meaning without leaves). Examples of mushrooms in this order include the chanterelles, boletes, and polypores. They play essential roles in ecosystems, decomposing wood and forming symbiotic relationships with plants.

Aphyllous

speak

Aphyllous means "without leaves" or referring to a plant that lacks leaves. It is often used in botany to describe plants that do not have visible leaves, or in cases where leaves are absent or highly reduced.

Apical

speak

Referring to the apical part or tip of a body part, such as the apical region of a tooth or the apical end of a nerve. It can also imply a relationship to the topmost point or summit.
