Arch-
This is a list of common affixes used when scientifically naming species, particularly extinct species for whom only their scientific names are used, along with their derivations. *a-, an-: ''Pronunciation'': /ə/, /a/, /ən/, /an/. ''Origin'': grc, ἀ-, ἀν- (''a, an-''). ''Meaning'': a prefix used to make words with a sense opposite to that of the root word; in this case, meaning "without" or "-less". This is usually used to describe organisms without a certain characteristic, as well as organisms in which that characteristic may not be immediately obvious. *:Examples: ''Anurognathus'' ("tail-less jaw"); ''Apus'' ("without foot"); '' Apteryx'' ("wingless"); ''Pteranodon'' ("toothless wing") *-acanth, acantho-, -cantho: ''Pronunciation'': /eɪkænθ/, /eɪkænθoʊ/. ''Origin'': grc, ἄκανθα (''ákantha''). ''Meaning'': spine. *:Examples: ''Acanthodes'' ("spiny base"); ''Acanthostega'' ("spine roof"); coelacanth ("hollow spine"); ''Acrocanthosaurus'' ("high-spined li ...

Affix
In linguistics, an affix is a morpheme that is attached to a word stem to form a new word or word form. Affixes may be derivational, like English ''-ness'' and ''pre-'', or inflectional, like English plural ''-s'' and past tense ''-ed''. They are bound morphemes by definition; prefixes and suffixes may be separable affixes. Affixation is the linguistic process that speakers use to form different words by adding morphemes at the beginning (prefixation), the middle (infixation) or the end (suffixation) of words. Positional categories of affixes ''Prefix'' and ''suffix'' may be subsumed under the term ''adfix'', in contrast to ''infix.'' When marking text for interlinear glossing, as in the third column in the chart above, simple affixes such as prefixes and suffixes are separated from the stem with hyphens. Affixes which disrupt the stem, or which themselves are discontinuous, are often marked off with angle brackets. Reduplication is often shown with a tilde. Affixes which c ...

Amphicyon
''Amphicyon'' ("ambiguous dog") is an extinct genus of large carnivorous bone-crushing mammals, popularly known as bear dogs, of the family Amphicyonidae, subfamily Amphicyoninae, from the Burdigalian Epoch until the late Pliocene, with the creature having bear-like and dog-like features. They ranged over North America, Europe, Asia, and Africa from 16.9 to 2.6 Ma ago, existing for approximately . Morphology ''Amphicyon'' was the typical bear-dog amphicyonid with morphology similar to both bears and dogs. With its robust build and maximum length of 2.5 m (8 ft), the largest species looked more like a bear than a dog. It had a large heavy tail, thick neck, robust limbs and teeth like a wolf. It was probably an omnivore with a lifestyle comparable to that of the brown bear. The ''Amphicyon'' was very large for predators of its time but this advantage eventually became a disadvantage because its large body mass was too large to take faster prey. ''A. major'' has been est ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
