The 'x' suffix is aviation speak in an abbreviated word called a contraction. You can think of the 'x' as "cut short" shorthand. Some are defined in manuals or advisory circulars. For example, WX is weather as defined in an old advisory circular, AC00-45.

MX - maintenance
CX - cancel
TX - transmit
RX - receive
