Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
1The action or process of lengthening something:‘the bird's tails become forked through elongation of their outer feathers’[count noun] ‘an elongation of the crater in the impact direction’
enlargement, increase in size, swelling, distension, dilationView synonyms

- ‘Both the computational and analytical models make mechanistic assumptions and do not explicitly deal with processes such as translational elongation.’
- ‘Some of the most frequent gross morphological adaptations to an aquatic lifestyle include the modifications of limbs into paddles and the elongation and lateral flattening of the tail.’
- ‘When mannerism dominated, there was also an emphasis on decoration inspired by animals, plants, and other themes that lent themselves to the elongation and distortion then prevalent.’
- ‘The lower maximum load used for calculation of graft elongations assured that values would be available for all specimens.’

- ‘Generally, with the elongation of the sidechain, the conformation change is significant and accompanied interaction variation is remarkable.’
- ‘To some degree, of course, this reflects simply the elongation of the body of the animal, but more prominently it represents the primary growth of the gastrointestinal tract itself.’
- ‘Dr Ewen believed he had established that something in the GM potato had caused elongation of a section of the stomach.’
- ‘In this case, however, shell inflation and posterior elongation of the aperture should be linked with each other, or the pattern of the aperture map must change considerably during ontogeny.’
- ‘Oberneder insists this is critical for getting true benefits from the motion, because when a muscle is stretched, its immediate reflex is to tighten up against the elongation.’
- ‘The development of a leaf involves a complex pattern of cell division and cell elongation, with cell elongation playing a central part in the expansion of the leaf blade.’
- ‘When that process happens, elongation of the hypocotyl, the embryonic stem, stops.’
- ‘The first step of longitudinal fission is the elongation of the body, causing the central tissues to experience stretch.’
- ‘Thus, the mechanical response in the adhesion geometry can be only partially estimated since adhesion induces strong elongations in the adhesive material.’
- ‘Another metabolite-specific effect seen in this work was hypocotyl thickening and elongation.’
- ‘The main difference in that study was the elongation of the tendons that were not surgically treated.’
- ‘In paralyzable detectors, a photon reaching the detector during the dead-time leads to an elongation of the dead-time period.’
- 1.1 An elongated part.
- 1.2 The amount of extension of an object under stress, usually expressed as a percentage of the original length.
protractedness, lengthiness, extent, extensiveness, elongationView synonyms
- ‘All structural metals have approximately the same ductility as measured by percentage elongation.’
- ‘Parts made from this material replicate polypropylene tensile strength and elongation at yield, and stuck in the elongation direction.’
- ‘The modulus is represented by the op line, the tensile strength by et, and the tensile elongation by oe.’
- ‘As-cast tensile strengths as high as 800 MPa and elongations of 15 to 20% can be obtained readily in sand castings, and slightly higher values in centrifugal castings.’
- ‘It is shown that tensile elongations between 150 and 200 percent can be obtained with all alloys under the appropriate conditions of temperature and strain rate.’
- ‘The relative amounts of elongation and spread cannot be calculated theoretically but they have been determined experimentally for mild steel.’
- ‘Some researches gave specific attention to cooling rate effects and increased tensile elongations obtained with slower cooling rates.’
- ‘However, austenitic steels possess very good ductility with elongations of about 50% in tensile tests.’
- ‘Lead may be added to the lower-strength manganese bronzes to increase machinability, but at the expense of decreased tensile strength and elongation.’
- ‘Also ductility, as measured by percentage elongation, decreases.’
- ‘The increase in gauge length related to the original length times 100 is the percentage of elongation.’
- ‘Fine-grained Ti - 6% Al - 4% V sheet can be superplastically formed, giving very high elongations, tight radii and negligible springback.’
- ‘By one treatment, the tensile strength and elongation may be substantially raised.’
- ‘The product in mind has a tensile elongation of 20% to 30%, which is a good quality in a concrete coating.’
- ‘Actone offers excellent flexibility, kink resistance, and torqueability as well as good pushability, a higher break load, and lower elongation.’
The angular separation of a planet from the sun or of a satellite from a planet, as seen by an observer:‘Mercury reaches greatest elongation on the 1st, when it will be 27 degrees west of the Sun’
- ‘The Sun keeps a tight rein on Mercury this month because the planet's greatest elongation falls on the day before its perihelion, when it is physically closest to the Sun.’
- ‘The planet reaches greatest eastern elongation, 23.5 degrees from the Sun, on the 3rd.’
- ‘On the 9th the planet is at greatest elongation from the Sun and sets around two hours after the Sun.’
- ‘Furthermore, any resonance with the Earth is illusory in that Mercury is not well placed for observations except during its brief greatest elongations near its aphelion.’
- ‘The planet attains its greatest elongation as early as June 8.’
Late Middle English: from late Latin elongatio(n-), from elongare place at a distance (see elongate).
