Possibly...particularly since much "wireless telegraphy" still used "spark
gap"
systems in those early years...! In fact, "Wireless telephony" was first
used
in (IIRC) 1906, when Reginald Fessenden (A Canadian!) used a high-
frequency "alternator" (AC generator) to provide the "carrier wave" for
his experiments in radio-telephony...amazing a few listeners with his
broadcast
of Christmas carols...!

Agreed...nonetheless, as you yourself point out, the "Y" ending covers the
practice...and the "E" (or none) describes any messages received thereby!
Thus, back when I was KN9JOO, I used "wireless telegraphy" (in fact, I
was a strictly-CW "ham!") to transmit information...!
BTW, "CW" stands for "continuous wave" because code transmission
consists of an interrupted (to match International Code...!) carrier wave
controlled by one's "key!"
And "Morse Code," developed for use in electrical telegraphy, is
different from "International Code"...particularly with respect to
numerals...!
In fact, back in 1949, I used to be a friend and sometime observer
of the chap who was the station agent...and thus telegrapher...of the
RR Station in Waynesville, Illinois! RR "telegraphy" used the Morse
code...the primary difference is/was in how numbers were represented!
