The notion of inflection comes from the Latin word inflection. The term has different meanings according to context .
An inflection can be a bow or one torsion of something that, until then, was flat or straight The concept also refers, in the field of geometry, to the point of a curve in which a modification of the direction of its curvature .
When the tone of voice is changed, attenuating or raising it, an inflection occurs. In the specific field of the grammar , meanwhile, an inflection or flexion is an alteration of certain voices that implies a change in the vowel of the root or in the termination to encode certain contents.
In other words, in linguistics the concept of inflection is defined as the change that words go through through constituent morphemes according to the categorical or grammatical meaning to denote their various functions in the context of a sentence , as well as their relations of agreement or dependence with other words or elements of the sentence.
He morpheme It is the smallest fragment with the ability to express a meaning and modify that of a lexeme by joining it. The lexeme, meanwhile, is an element that has a referential meaning, that is, when combined with a word produces an idea that the speaker can understand.
Traditional grammar recognizes more than one name for inflections, depending on the kind of words to which they apply. On the one hand we have the verbal inflection , which is also known by the name of conjugation. The nominal inflection , on the other hand, it is also called decline; In Indo-European languages (the largest family of languages, in which almost all of those spoken in Europe and South Asia are found), this is usually applied to adjectives, nouns and pronouns.
When the morpheme is added to the root of the word, the so-called radical inflection while the thematic It takes place when added to the topic. Every segment that is added to indicate an inflection accident is known as ending .
Through verbal inflections we can specify issues such as time, the mode , the person and the number, all variations that we understand within the concept of conjugation. For example, "comO" is not the same as "COMMISS." Nominal inflections, meanwhile, allow us to recognize the gender and number of adjectives and nouns, among other aspects. In this way, we can know that "gatOS" are two or more and that they are male or that their sex is not known, while "gatA" is only one and female.
In our language, interjections and prepositions, among other categories, are considered invariable words because they do not admit inflections; In other words, its form never changes.
If we focus on the geometric scope, it is called inflection point to the point where a function ceases to be convex to become concave or vice versa. In the graph, this transformation is seen as a change in the direction of the curve.
At the inflection points, the derived function reaches its minimums and maximums. The function It grows more and more until it reaches the point of inflection: when it is exceeded, it begins to grow less.
For the climatology , the turning point is the passage of a state stable towards another. It is, therefore, a transition .
In the linguistics Finally, an inflection is an alteration that is recorded in a term through morphemes that allow you to express various functions in a sentence and specify relationships of agreement or dependence with other elements.
