Do a little research of your own H20.
This one concerns Yehova:

In Judaism, the Tetragrammaton is the ineffable name of God
According to one Jewish tradition, the Tetragrammaton is related to the causative form, the imperfect state, of the Hebrew verb ha·wah [הוה] (become); meaning "He will cause to become" usually understood as "He causes to become". Compare the many Hebrew and Arabic personal names which are 3rd person singular imperfective verb forms starting with "y", e.g. Hebrew "Yôsêph" = Arabic "Yazîd" = "He [who] adds"; Arabic "Yahyâ" = "He [who] lives.
As does this article explain that Yehova is a personal name with a meaning.
What does Allah mean then?
let's see:

It should be noted that many linguists believe that the term Allah is derived from a contraction of the Arabic words al (the) + ilah (male deity). In addition, one of the main pagan goddesses of pre-Islamic Arabia, Allat (al + ilah + at, or 'the female deity'), is cited as being etymologically (though not synchronically) the feminine linguistic counterpart to the grammatically masculine Allah. If so, the word Allah is an abbreviated title, meaning 'the deity', rather than a name. For this reason, both Muslim and non-Muslim scholars often translate Allah directly into English as 'God'
