List and explain three major ways that words in a language change overtime. use complete sentences in your response. consider using examples.

An example would be the word nice. Nice used to be an insult and meant foolish or stupid in the 13th century and it went through many changes right through to the 18th century with meanings like wanton, extravagant, elegant, strange, modest, thin, and shy or coy. Now it means a good & pleasing or thoughtful & kind. Silly meant blessed or happy in the 11th century and went through pious, innocent, harmless, pitiable and feeble minded before ending up as foolish or stupid. Pretty started as crafty this changed to clever or skillfully made, then to fine and ended up as beautiful.

There are several reasons for words change meaning. One is the influence of other languages and cultures. Throughout history, many nations through conquering or intermixing with one another, introduced their own languages into the mix. Another reason is the predominate use of slang words. We get so used to using them that many times we forget that we even are.

So when it comes to defining words, there is the standard dictionary, which by the way can show multiple meanings for one word, and there is the definition of the word in slang. 
As well, slang words spread faster and are used more often than before, making them common place in many societies. Hope this helped!!

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
