المثلث اللغوي في كتاب (الدر النقي في شرح ألفاظ الخرقي)‎ لابن المبرد (ت909ه)‎

Abstract EN

What linguists do in controlling the Arabic language's words, especially controlling the letters rather than vowels, is the best evidence of their keenness and knowledge of those words, because any change in the structure of the word may be accompanied by a change in the significance of that word, and it may lead to the wrong meaning.

Pay attention to the words of the Arabic language, especially those that are similar in their forms and letters, and differ in the movement of their fa'a or its eye, which is known as (the linguistic triangle).

Among those who took care of these terms was Ibn al-Mubarrad, who realized the great benefit that occurs when knowledge of those words, and the great danger that occurs when ignorance of them and turning away from them, and that the likeness of words is a phenomenon (the linguistic triangle) if the meanings of them are not known and the passage of them is known.

Time changes the meaning of the word, so the three words with different meanings may become one word in exchange for these connotations, that is, we entered into the phenomenon of the verbal common, a word against different meanings, and the truth is that these different meanings are different punches as well, and what happened is the result of lack of control and knowledge.

Such words, and from here it became necessary for us to study the vocabulary of this phenomenon.
