"هل" is an Arabic particle used to form yes-or-no questions. It is placed at the beginning of a sentence to indicate that a question is being asked. For example, in the sentence "هل تحب القهوة؟" (Do you like coffee?), "هل" signals that the speaker is seeking a confirmation or denial. In addition to its use in questions, "هل" can also be used to emphasize a statement. It helps clarify the intent of the speaker, making it easier for the listener to understand that a response is expected. This particle is essential in everyday Arabic conversation, enhancing communication clarity.
