Present participle of elate; in the process of making someone extremely happy, proud, or excited.
From Latin 'elatus' (lifted up) with the present participle suffix '-ing' (from Old English '-ung'). The '-ing' form creates a verbal noun or gerund describing the ongoing action of lifting someone's spirits.
The '-ing' form is interesting because it can be both a verb ('the news is elating her') and a noun ('elating others is his gift'), showing how English particles create grammatical flexibility that other languages achieve through different means.
