La estructura interna de la palabra
1. Los formantes morfológicos Una palabra tiene estructura interna cuando contiene más de un formante morfológico. Un formante morfológico o morfema es una unidad mínima que consta de una forma fonética y de un significado. Comparemos las siguientes palabras: gota, gotas, gotita, gotera, cuentagotas. Gota es la única de estas palabras que consta de un solo formante. Carece, entonces, de estructura interna. Es una palabra simple. Todas las otras palabras tienen estructura interna. [31] Los formantes que pueden aparecer como palabras independientes son formas libres. Los otros, los que necesariamente van adosados a otros morfe- mas, son formas ligadas. Cuentagotas contiene dos formantes que pueden aparecer cada uno como palabra independiente. Es una palabra compuesta. Gotas, gotita y gotera también contienen dos formantes, pero uno de ellos (-s, -ita, -era) nunca puede ser una palabra independiente. Son formas ligadas que se denominan afijos. Algunos afijos van pospuestos a la base (gota), como los de nuestros ejemplos: son los s u f i j o s . Otros afijos la preceden: in-útil, des-contento, a-político: Son los prefijos. Las palabras que contienen un afijo se denominan palabras complejas. Del inventario de formantes reconocidos, reconoceremos dos clases: a. Algunos son formantes léxicos: tienen un significado léxico, que se define en el diccionario: gota, cuenta. Se agrupan en clases abiertas. Pertenecen a una clase particular de palabras: sustantivos (gota), adjetivos (útil), adverbios (ayer), verbos (cuenta). Pueden ser: - palabras simples (gota, útil, ayer); - base a la que se adosan los afijos en palabras complejas (got-, politic-); - parte de una palabra, compuesta (cuenta, gotas). b. Otros son formantes gramaticales: tienen significado gramatical, no léxico. Se agrupan en clases cerradas. Pueden ser: - palabras independientes: preposiciones (a, de, por), conjunciones (que, si); - afijos en palabras derivadas (-s, -ero, in-, des-); - menos frecuentemente, formantes de compuestos (aun-que, por-que, si-no). Entre las palabras no simples consideradas hasta aquí, cada una contenía sólo dos formantes. En otras un mismo tipo de formantes se repite: - sufijos: region-al-izar, util-iza-ble; - prefijos: des-com-poner. ex-pro-soviético, o también formantes de diferentes tipos pueden combinarse entre sí: - prefijo y sufijo: des-leal-tad, em-pobr-ecer; - palabra compuesta y sufijo: rionegr-ino, narcotrafic-ante. En la combinación de prefijación y sufijación, se distinguen dos casos, ilustrados en nuestros ejemplos. En deslealtad, la aplicación de cada uno de los afijos da como resultado una palabra bien formada: si aplicamos sólo el prefijo se obtiene el adjetivo desleal; si aplicamos sólo el sufijo el resultado será el sustantivo lealtad. En cambio, en empobrecer, si se aplica sólo un afijo [32] el resultado no será una palabra existente: *empobre, *pobrecer. Prefijo y sufijo se aplican simultáneamente, constituyendo un único formante morfológico – discontinuo– que se añade a ambos lados de la base léxica. Este segundo caso se denomina parasíntesis. Para establecer la estructura interna de las palabras, la morfología se ocupa de: a. identificar los formantes morfológicos; b. determinar las posibles variaciones que éstos presenten; c. describir los procesos involucrados; d. reconocer la organización de las palabras. 2. Identificación de los formantes morfológicos Comparemos ahora las siguientes palabras: sol, sol-ar; sol-azo, quita- sol, gira-sol, solter-o, solaz. En las

The results also highlight the ability of MRI in the detection of more aggressive types of cancer.

zed by many buyers and sellers, many products that are similar in nature and, as a result, many substitutes. Perfect competition means there are few, if any, barriers to entry for new companies, and prices are determined by supply and demand. Thus, producers in a perfectly competitive market are subject to the prices determined by the market and do not have any leverage. For example, in a perfectly competitive market, should a single firm decide to increase its selling price of a good, the consumers can just turn to the nearest competitor for a better p

Firms are said to be in perfect competition when the following conditions occur:

Many firms produce identical products.
Many buyers are available to buy the product, and many sellers are available to sell the product.
Sellers and buyers have all relevant information to make rational decisions about the product being bought and sold.
Firms can enter and leave the market without any restrictions—in other words, there is free entry and exit into and out of the market.

sellers are price takers. The market structure is the conditions in an industry, such as number of sellers, how easy or difficult it is for a new firm to enter, and the type of products that are sold.
