Words Starting With "R"
Our pre-recorded sounds are fast, clear, and natural, spoken by native speakers.
Rhus
The word "rhus" can refer to several things, but the most common meaning is a genus of flowering plants in the family Anacardiaceae, commonly known as the sumac or poison ivy genus, native to warm temperate and tropical regions around the world.
Rhusiopathiae
Epizootic lymphangitis or cutaneous blastomycosis is caused by the fungus Histoplasma capsulatum or the closely related Rhinosporidium seeberi and the Leishmania parasites but most commonly by a Rhinosporidium seeberi.
Rhyacotriton
A rare one!<br><br>Rhyacotriton is not a commonly known word, but it seems to be a genus of salamanders.<br><br>Rhyacotriton is a genus of aquatic salamanders in the family Rhyacotritonidae. They are endemic to the Pacific coast of North America.<br><br>Note: The scientific name "Rhyacotriton" is derived from Greek words "rhyákos" (ῥυάκος), meaning "rushing" or "swift", and "tritōn" (τρίτων), meaning "three" or " sea-god", a reference to the salamander's aquatic habitat.
Rhydectomy
Rhydectomy is a surgical procedure to remove or reposition the earlobe, often to correct a condition known as lop ears or carry the weight of an implant (e.g., to resolve "implant annoyance" while supporting a prosthesis).
Rhyme
The word "rhyme" refers to a word or phrase in which the final phonemes (units of sound) sound the same, typically in a poem or song.
Rhymes
The word "rhymes" refers to words that have the same ending sound or syllables. In poetry, music, and speech, rhymes are used to create a musical quality, often to add structure, emphasis, or emotional effect. Rhymes can be perfect (exact matches), slant (almost identical but not exact), or eye (visual rhymes, where the final words look similar but not sound identical).
Rhyming
Also known as rhyming words, rhyming is the repetition of identical sound in two or more words, usually at the end of a line in poetry or music. Rhyming is a poetic device used to add musicality and structure to written or spoken language, making it more memorable and aesthetically pleasing.
Rhymist
There is no word "rhymist". However, I'm guessing you meant "rhymer".<br><br>A rhymer is a person who creates rhymes, often as a poet or songwriter.
Rhynchocephala
A group of reptiles that includes the horned lizards and the iguanas. The name Rhynchocephala means "beaked head" in Greek. They possess a distinctively shaped, projecting snout in the front of the head, which gives them a horn-like appearance.
Rhynchocephalia
Rynchocephalia is a now-abandoned term in paleontology that refers to a group of jawed vertebrates, but now the preferred term is "parasphenoid- palate craniates."
Rhynchocephalian
A fossil group made up of extinct lizards, characterized by the presence of teeth pointed forward instead of being side-by-side like many modern lizards, and a relatively long, pointed snout (the Greek word "rhynch-" meaning 'beak' or 'snout', 'kēphalē' meaning 'head').
Rhynchocoel
A term that's definitely not commonly used in everyday conversation!<br><br>A rynchocoel refers to a type of coelomate, which is an animal with a body cavity. In particular, it refers to a specific type of embryo that develops into a pseudocoelomate, which is a type of animal that has an incomplete digestive system and a so-called "pseudocoelom" or "false body cavity" rather than a true coelom (a body cavity lined with peritoneum).<br><br>In other words, a rynchocoel is an embryo at a stage of development that has not yet differentiated into a fully formed coelomate.
Rhynchocoela
Rynchocoela refers to a category of nudibranchs, which are a type of sea slug, a marine gastropod mollusk. Rynchocoela is characterized by the presence of a rhytisome – a sort of wing-like appendage or flap.
Rhyncholite
A rhyncholite is any rock that contains yellow calcite crystals on cleavage joints. The term is particularly used for rhodonite.
Rhynchonellida
Rhynchonellida is an order of marine bryozoans, which are small, colonial, sessile, and metameric animals with a calcareous exoskeleton. The name "Rhynchonellida" may be derived from the Greek words "rhynchos" (ῥυγχος), meaning "beak" or "snout", and "onella", a diminutive form of "onkos", meaning "shoulder" or "body".
Rhynchonellids
Rhynchonellids are a type of brachiopod, a phylum of marine animals that are commonly known as lamp shells. They are known for their unique, lophophorate (feathery, tentacle-like) feeding structures and articulate, calcareous shells. Believe it or not, rhynchonellids have been around for a long time – their fossils date back to over 480 million years ago during the Cambrian period.
Rhynchophora
Rhynchophora is a superfamily of weevils, particularly the weevils of the tribe Rhynchophorini. The name rhynchophora, translated from Greek, means "snout-bearing ones" due to the distinctive shape of the weevils' heads, which they use to feed on plants.
Rhynchophore
A tongue-twisting word!<br><br>A rhynchophore is a part of a gastropod mollusk, specifically a type of radula at the front of the mouth. It is a beak-like structure that is used to scrape or scrape food particles from surfaces.<br><br>In other words, a rhynchophore is a special appendage found in snails and slugs that helps them to eat and feed on algae, plants, and other small organisms.
Rhynchosaur
The rhynchosaur is a type of archosaur that lived during the Middle to Late Triassic period, around 230-205 million years ago. They were carnivorous reptiles with a distinctive pair of horn-like crests on their snout, which gave them their name. Rhynchosaurus were likely ambush predators, using their short, broad snout and powerful jaws to grab prey.
Rhynchosauria
Rhychnosauria is a group of archosaurs, specifically a subclade within the larger group Archosauria, which includes dinosaurs and their closest relatives. It is a distinctive group of carnivorous reptiles that lived during the Middle to Late Triassic period, around 245 to 221 million years ago.<br><br>Rhychnosauria is characterized by the presence of a distinctive pair of claw-like structures on the snout, which are known as rhamphotheca or rhachydont teeth. These structures were likely used for tearing flesh and ripping apart the skin and muscle of their prey.<br><br>Some notable characteristics of the Rhychnosauria group include:<br><br> Large size, typically around 1-5 meters in length<br> Elongated, crocodile-like body<br> Powerful jaws with sharp teeth and rhamphotheca<br> Webbed feet<br> A combination of rigid, bony scales (scutes) and flexible skin<br><br>The Rhychnosauria group gave rise to several notable subgroups, including the Proterosuchidae and Rhychnosuchidae families.
Rhynchospora
Rhynchospora is a genus of sedges in the family Cyperaceae, commonly known as beak sedges or beaked sedges. The genus contains about 100 species, mostly found in tropical and subtropical regions of the world.
Rhynchostylis
Rynchostylis is a type of orchid genus native to East Asia, specifically in China, Japan, and Korea.
Rhynchota
The term "Rhynchota" refers to an archaic order of insects, which is now commonly classified as the superorder Rhynchnotodea or more specifically, as consisting of two distinct orders: Coleoptera (beetles) and Hemiptera (true bugs, cicadas, and aphids).
Rhyncostylis
Rhyncostylis is a type of orchid genus, native to Southeast Asia. It is a flowering plant with distinctive, funnel-shaped flowers.
Rhynia
Rhynia refers to a genus of ancient lycopodiophytes (or lycopods), a group of vascular plants that are more than 400 million years old. These plants are considered to be some of the earliest known vascular plants on Earth and are often discussed in the context of the evolution of plants.
Rhyniaceae
The Rhyniaceae is a family of extinct plants which belongs to the division Rhyniophyta, a group of vascular plants that lived around 416 to 410 million years ago during the Silurian Period.
Rhyniophyta
Rhyniophyta is a division of vascular plants that lived during the Silurian and Devonian periods. They are among the earliest vascular plants, which are the earliest ancestors of modern plants. The term "Rhyniophyta" comes from the Rhynie Chert, a type of sedimentary rock in Aberdeenshire, Scotland, which contains well-preserved fossils of Rhyniophyte plants.<br><br>These plants were characterized by their small size, simple structure, and lack of roots, stems, and leaves as seen in modern plants. They had a dichotomous branching structure, with leaves that were attached at the tips of short rhizoids (branching underground stems that anchor the plant). Rhyniophytes were likely small and simple organisms that obtained nutrients and water from their surroundings. They paved the way for more advanced plant life, including those that would eventually develop into trees, ferns, and all other types of vascular plants.
Rhynophyma
A rare skin condition characterized by a bulbous nose, large pores, and a cluster of red, swollen blood vessels, often resulting from rosacea.
Rhynoplasty
Rhinoplasty is the surgical reconstruction or repair of the nose, often performed to improve its appearance or to correct breathing problems.
Rhyolite
A type of volcanic rock formed from the rapid cooling of lava flows that contain high levels of silica.
