English: torpedo tube
German: Torpedorohr
KGT p. 56: Ships are also equipped with an explosive weapon called a peng, usually translated as "torpedo," though "missile" might work just as well. The plural form of peng is a different word, cha. A peng is launched from a tube usually called a DuS, but another term, chetvI', is also used, the distinction having something to do with how the projectile is actually loaded into the tube. The verb used for "launch" or "fire" a weapon of this type is baH, and there is even a special word, ghuS, meaning "prepare to launch." The warhead of the torpedo is called its jorneb (which seems to contain the verb jor ["explode"] but is otherwise not analyzable).
English: Chetvi, spear-throwing device
KLCP:
KGT p. 64: There is, in addition, at least one type of spear, the tlhevjaQ,which employs a chetvI', a stick with a hook at the end, as an aid forthrowing. There is a single verb, wob, that is used to describe the fullrange of activities involved in putting the spear properly into the spear-throwing aid and using the air to hurl the spear: tlhevjaQ wob ("He/she puts the tlhevjaQ into the chetvI' and hurls the spear"). In speaking of this type of spear and spear-throwing technique, it is still proper to use theverb chuH when talking about throwing the spear at a target.
