Words can be changed through morphemes. In the field of linguistics this phenomenon is known as flexion. In other words, words have a number of possible changes; for this, the union of flexive morphemes to a base is necessary.
Flexive morphemes are generally mandatory and form a closed model, since there is not an infinite number of flexive morphemes. In short, it is one of the processes that allows you to create a new word.
Four simple bending examples
1) The word “white” has a base, more specifically blanc. From it, a gender and number inflection is necessary. Thus, with an “a” and an “s” we form the word white.
2) In the word “maestro” we have a lexeme or base (maestr) and another masculine flexive morpheme .
3) Verbal forms also apply the same process . Thus, the form “cantaria” is composed of the lexeme sings, plus the flexive morpheme laughs.
4) The verb forms “bring, bringing and bringing” have the same lexeme, but each one has a specific flexive morpheme.
We must not confuse flexion with derivation
To form words there are two different processes: inflection and derivation. In the first case, a new word is not created, while in the second a new term is possible. In this way, through the derivation, a base or lexeme is joined with a derivative morpheme.
From the adjective white, an abstract quality can be created by adding a derivative noun (ura) and thus forming the word whiteness.
The two ways to form words are due to the fact that there are two types of morphemes: inflective and derivative
In the former, information of the grammatical type is added , which can be nominal flexive morphemes or verbal flexive morphemes. On the other hand, derivative morphemes provide a change of meaning and this causes the adjective to become a noun (for example, white and white) or by introducing a prefix (for example, the prefix pre and the word to make the term predict).
The study of inflection and derivation is part of morphology, an aspect of linguistics which is the discipline that studies the structure of language . In short, morphology focuses on the structure and formation of words, whereas linguistics studies the structure of a language.
