Why do we have these chess terminologies?

Strong/weak players instead of good/bad players, strong move

Blunder instead of terrible

Draw instead of tie

Sound opening instead of good opening

Arbiter instead of referee

My impression is that, historically, “blunder” was used to suggest that a terrible move was some sort of aberration that would not necessarily be reflective of an individual’s usual quality of play.

For some time, it has bothered me that there seem to be variations in the usage of “sound”, but the general sense seems to me to be close to “acceptable, but not necessarily good”.

As far as I can tell, “draw” and “arbiter” are simply the words that have become traditional in chess circles. Anyone know why bridge players refer to the deuce instead of the two?

Why would you even think these are chess specific terms?
