Heil Hitler
The basic meaning of Heil is to wish you good luck. You can add the third object "Heil dir" (Wish you good luck). This word can also appear in, for example, "Ski Heil" (safe skiing), "Petri Heil" (wish you catch a big fish), etc.
In the phrase "Heil Hitler", the hope in this greeting is actually closely related to the status of the person being greeted, aiming to overcome the inaccessibility between people in the world. In a religious sense, this means a form of life that is consistent with the self and is neither destroyed by practice nor damaged by the transience of nature. In this reading, "Heil" actually reflects the existence of God, and such an existence is the only way to reflect the pure form of "Heil". It can be further transformed into the relationship between the ruler and the ruled, and used as a daily formula to enter greetings. On the contrary, it is used deliberately to express a wish when paying tribute to the emperor or the motherland, or when expressing greetings to the person in power or the imagined political community. This wish can either be expressed to the monarch in person, which of course requires the monarch's presence; or it can be stated clearly on the occasion of a certain democratic community confirming the unity of its members - such as "Long live Germany", "Fatherland" Long live” and so on. In the above explanation, "Heil" is actually a greeting in public events. Rather than saying that it occurs at the beginning of an encounter between people, it is rather that it is often located at the end of the encounter, becoming a declaration of unity facing the unknown future or upcoming challenges.
