How did the word Hola come from?

1. This series of words became popular when Edison advocated using hello on the phone in 1833, and countries began to use the homonym of this English word to say hello.

But this statement is untenable, because the usage of hallo appears in 178 1, and forms of address like hollo and holla appear in 1580.

2. From Greek? λ ε (→ le), which means "salve" (a way to say hello, which is common in poetry and has the meaning of wishing good health), because this word is used in the 403rd sentence of Volume 24 of the Odyssey:

Salve(ο？ λ ε), sé muy dichoso, and las deidades de concept to class de venturas.

It sounds reasonable, but some opponents think that Hola doesn't mean to wish good health, and the pronunciation of this word is not so similar.

3. This word comes from German Heilen (cure, wish others health). After the fall of the Roman Empire, it was spread to France by Germans and became Hélas, expressing a sigh, and later spread to other countries.

There are also many people who refute this statement. Their reason is that in German, Heil is generally used to modify Heilen instead of verbs, and its meaning is still far-fetched.

4. The 4.HOLA series is derived from Latin and is a combination of modal particles and locative words. The Latin words for "here" or "there" are illuc and illac respectively. After adding the modal particle ho in front of them, it becomes ho-illuc, ho-illac. Ho-illuc and ho-illac gradually became holla and hollo in the process of communication and evolution. According to people's language preference in a specific region, some people like to say "Hey, this way" when greeting others, so they use hollo, while others use "Hey, that way" and Holla. Today, Hello/ hallo and hola/ola are different.
