The most interesting word certainly is {nu'}. To show the difference: a
{targhHom} is just a small targ, but a {targh nu'} can only refer to a
"toy targ". 

 Okrand's words:
------
There's no noun Maltz is aware of like "miniature" (small model or
version of something).  {machqu'} is fine, but if you want to avoid it,
you could use the verb {nu'} which means something like "be particularly
small" and is often used of things that are smaller than the usual or
expected size. In general, things that are {nu'} are smaller than those
that are {mach} or even {machqu'} — but there's no hard line or specific
rule. If/when it's appropriate, you could also make use of {-Hom}.
