What does HT mean in "HT radio"

What do the 2 letters stand for?

Obviously the expression describes hand held radios,
but I cannot find an explanation.

"Handie-Talkie" (or variations on the spelling thereof).

This was originally a brand-name term for the Galvin (think
"Motorola") SCR536 portable radio, introduced in 1940. The
abbreviation "HT" has since been co-opted by hams (and perhaps others)
to refer to almost any hand-held portable UHF/VHF radio.
