Best Answer Explained in Below-:

In the phrase "Down with tyrant! Here down," the word "down" functions primarily as a verb. In this context, "down" acts as a form of exclamation or imperative, calling for a action or expressing a sentiment toward tyrants—a call to resist or overthrow a tyrannical power. The use of "down" here commands an immediate reaction or movement against oppression, emphasizing a strong, action-oriented message.

While "down" can serve as other parts of speech, such as an adjective (e.g., describing something that is lower) or a preposition (e.g., indicating direction), its function in this sentence points to an imperative form of a verb. The phrase suggests the act of bringing down or dismantling a tyrant's authority. Therefore, interpreting "down" as a verb captures the essence of the action being advocated in the statement. This linguistic strategy contributes to the rallying cry against tyranny, aligning the word with the context of resistance and empowerment.
