1. 1.1 Right-handed.

  The literal-minded dextral dwarfs of the right-wing press are undone somewhat by irony and wit, especially since they believe they are uniquely blessed with a ‘sense of humour’.
2. 1.2Geology Relating to or denoting a strike-slip fault in which the motion of the block on the further side of the fault from an observer is towards the right.
  〔地质〕（走滑断层）右旋的
  Example sentencesExamples
  In the northern Musgrave Block the Petermann Orogeny generated large-scale east-west-trending shear zones that accommodated dextral strike-slip and north- and south-directed thrusting.

  In fact, Aleksandrowski et al proposed that the complex was originally contiguous with the Northern Phyllite Zone in Germany and that dextral strike-slip fault movement translated this region southeastward to its present position.
  The Murzinka-Adui Metamorphic Complex to the SE of the Salda Complex is separated from the latter by the Petrokamensk Arc and the Sisert dextral strike-slip fault.
  It is commonly assumed that the Stanovoy sinistral shear zone and the Sakhalin-Hokkaido dextral shear zone in NE Asia are two conjugate strike-slip faults related to the India-Eurasia collision.
3. 1.3Zoology (of a spiral mollusc shell) with whorls rising to the right and coiling in an anticlockwise direction.
  〔动〕（软体动物螺壳上的螺线）右旋的，逆时针方向卷的
  Example sentencesExamples
  So the spiral of the operculum of a dextral (right-handed) snail is invariably counterclockwise, while that of a sinistral shell is the opposite.
  Sinistral individuals in normally dextral populations often deviate slightly in shell form from wild-type dextrals, perhaps implying that the left-handed condition has small deleterious side effects.
  In plan view, several specimens show minor changes in the generally linear orientation with either a sinistral or a dextral turn.
  Nevertheless, sinistral and dextral Pb elements are virtually mirror images, that is, they are more alike than the corresponding elements in L. variabilis.
  There are dextral species, sinistral species, and a variable species (P. suturalis-see below) all within the same genus.

noun ˈdɛkstr(ə)lˈdɛkstrəl

A right-handed person.
惯用右手的
Example sentencesExamples
- The five superfamilies shown in Figure 2 depict the five kinds of clade found with respect to the occurrence of sinistrals and dextrals: sinistrals only; majority sinistral; very heterogeneous; majority dextral; dextrals only.

dextrality

noun dɛkˈstralətidɛkˈstrælədi

Example sentencesExamples
- Annett, M., Eglinton, E., Smythe, P. were the authors of Types of dyslexia and the shift to dextrality.
- It is possible that other commissural systems that transmit motor commands and thus influence dextrality may also manifest sexual orientation-related differences.

- But when they were actively seeking out shellfish using their favoured flipper-beating technique, the walruses used their right flipper - a trait known as dextrality - 89 per cent of the time.

dextrally

adverb

Clockwise rotation of the trend of volcanic ridges is associated with dextrally offset, sinistrally slipping transforms, while anticlockwise rotation is associated with sinistrally offset, dextrally slipping transforms.
Example sentencesExamples
- Both species described here are sinistrally coiled, but a similar pattern of ornamentation is present on two Pennsylvanian species that are dextrally coiled.
- Thus, the gerontic aperture of these dextrally coiled shells is situated on the left side in apertural view.
- Similar to all Porcellioidea, the shell axes of the dextrally coiled early shell and teleoconch are parallel (anastrophy).
- The outer shell surface of both sinistrally coiled species of Crassimarginata is ornamented by distinct costae, but the dextrally coiled shells of Yukonoconcha seem to be smooth.

Origin

Mid 17th century: from medieval Latin dextralis, from Latin dextra 'the right hand', from dexter 'on the right'.
