cello versus 'cello

Why do some people prefer writing this word as 'cello just to show that it's short for ''violoncello'' note that it is not ''violincello''.

"Cello" is the word we all know and by which we refer (and will continue to refer) to the instrument.

''Cello'' is short for ''violoncello''. It should be written ''cello'' not '' 'cello ''. Oh, and it's pronounced [chelOu].

Yes. "Bus" is short for "Omnibus" but we don't say " 'bus".

Ne-vamble-da

... nor do we write "'phone" or "'plane" though their short for "telephone" and "aeroplane".

Ne-vamble-da is a state in the United States yeah, I repeat ''ne-vamble-da''.

You don't write 'phone and 'plane because both ''telephone'' and ''phone'' and both ''airplane'' and ''plane'' are really common. But ''omnibus'' and ''violoncello'' are not often heard. ''Bus'' and ''cello'' are most often heard and some people don't even know that those two words are short for something. Jim says ''nor do we write "'phone" or "'plane" though their short for "telephone" and "aeroplane".'' Correct-''their'' should be ''they're''.

Yeah, "they're" not "their". I don't think that there's any need for the apostraphe in any of these words.
