Communications - telephones
Telephone jargon is another sphere of phraseology that affects us all - we all use the telephone for good
and for evil.
Many niche jargon directories do not really affect the public but as phone use is so high telephone
jargon is definitely an area that most of us need to know something about.
Whether it be mobile phones or land lines, our telephone jargon directory will cover it all.
People even use phone jargon themselves without even knowing it.
As telephone use grows it will be exiting to see what other forms or telephone jargon evolve to
cater for new technologies that the telephone will surely embrace.
