One of the mysteries of the English language finally explained.
A grinding tooth at the back of a mammal's mouth.
- ‘All animals in this order lack incisor and canine teeth, but they may have numerous simple molars in the backs of their jaws.’
- ‘The molars are stationary, that is, they don't show pattern of forward movement with aging that is seen in macropodids.’
- ‘The location of early caries is found most often in children's maxillary incisors and first molars.’
- ‘The medical name for wisdom teeth is the third molars.’
- ‘Gum disease can affect the first and second molars and the bone surrounding the tooth, as well as the impacted wisdom tooth.’
- ‘They may still require assistance in brushing their teeth - especially the back molars.’
- ‘In contrast to man, apes tend to have large incisor and canine teeth which are relatively larger than their molars.’
- ‘For years, our Scandinavian cousins put us to shame with their gleaming molars and incisors.’
- ‘Three weeks after birth, pigs have their first deciduous molars in occlusion and show large and often clumsy jaw movements.’
- ‘Each half of a manatee's jaw has five to eight molars which, unusually, are continuously replaced throughout its life.’
- ‘Use a piece of unflavored, unwaxed dental floss and floss between your upper and lower back molars.’
- ‘At eighteen months, Monica has just this week cut two of her three emerging molars, which had been bulging and sore for weeks.’
- ‘The teeth most often missing are the third molars, second premolars, and maxillary lateral incisors, and other teeth may be reduced in size.’
- ‘An examination of the mouth revealed molars that had broken off at the gum line.’
- ‘The molars' purpose is to grind food, and the incisors and canine teeth are used to bite into and tear food.’
- ‘This wasn't entirely unexpected; she's cutting molars and we often have a few nights with some stirring when that's going on.’
- ‘He's got a tooth, one of his molars, that's causing him a lot of pain and will probably need to be removed.’
- ‘Year nine pupils are letting dentists examine their molars as part of a national review aimed at improving the nation's gnashers.’
- ‘The first permanent molars stabilize the dental arch and have a great deal to do with the ultimate shape of the jaw and orderly arrangement of teeth.’
- ‘My teeth are as white as the moon, an orderly upper and lower row of molars and incisors with long, sharp fangs, on both the top and the bottom.’
Late Middle English: from Latin molaris, from mola ‘millstone’.
Relating to mass; acting on or by means of large masses or units.
- ‘The experiments with the solids mostly involve oxidation reactions, measuring the water of hydration, and finding the molar mass by titration.’
- ‘He couldn't even find the molar mass of water.’
- ‘A point in an absorption spectrum at which two or more components have the same molar magnetic susceptibility is termed an isosbestic point.’
- ‘This demonstration exploits biophysical models of energy flux coupled with molar balance models of mass flux and GIS-based information on climate, topography, and vegetation.’
- ‘The fetus was displaced toward the right by an enhancing cystic mass compatible with a molar pregnancy.’
Mid 19th century: from Latin moles ‘mass’ + -ar.
1Relating to one mole of a substance.
- ‘Anaesthesia commences when any chemically indifferent substance has achieved a certain molar concentration in the lipoids of the cell.’
- ‘Uncharged polar and even ionic dyes with substantial molar weights have often been used to trace apoplastic water movement.’
- ‘Both are acceptable in SI, but mg/l is a mass unit and mol/l a molar unit.’
- ‘Another substantial advantage is that volume fractions and molar concentrations are easily interconvertible, making comparison with experimental papers easier.’
- ‘The enthalpy change that occurs during the complete combustion of one mole of a substance is called the molar heat of combustion, symbolized H c o.’
- 1.1 (of a solution) containing one mole of solute per liter of solution.
- ‘The section on the interconversion of molal and molar solutions needs to be reworded.’
- ‘We carried out MD simulations for six different halothane/lipid molar concentrations ranging from 0: 512 to 512: 512.’
- ‘Tests demonstrate that the amount of available zinc is much higher in an herbal preparation than in an equal molar amount of zinc sulfate, and the clinical effects are noticeably greater.’
- ‘An example of this would be describing a solution as a 1 molar solution, or saying it had a strength of 1 M.’
- ‘In this case a solution that was 0.9 molar in trehalose and sucrose was examined for a sample at known spacing as described for water.’
