  • $\begingroup$ Mainly to distinguish it from an "atom bomb", which is a fission-based nuclear weapon. $\endgroup$

Its called "thermonuclear" because its energy producing nuclear fusion reaction is started by the extremely high temperatures of a nuclear fission bomb.

  • $\begingroup$ Nuclear fission isn't the only way to get a thermonuclear reaction started; it's just the easiest in a bomb. A controlled thermonuclear reaction would be stated a different way. $\endgroup$
