Brahmā (ब्रह्मा) who is the creator aspect of the Trimurti God, while Vishnu (विष्णु) and Shiva (शिव ) being the Preserver and the Destroyer aspects.

The most frequently used etymological meaning for Vishnu and Shiva which I have encountered almost everywhere is :-

*Vishnu (विष्णु)* = The all pervader, who is everywhere, all pervading. The One who enters (everywhere?), etc.

*Shiva (शिव )* = The all auspicious one, the one who's Pure and the most auspicious, etc.

For the word *Brahmā (ब्रह्मा)*, I haven't found anywhere, any proper etymology and meaning.

I'd like to know (with scriptural as well as non-scriptural references too) all possible etymology and meanings of all of the *Trimurtis - Brahmā, Vishnu, Shiva*, with specific emphasis on *Brahmā (ब्रह्मा).*
