Considering that some adverbials, like {motlh}, are also verbs, I have long wondered if one can essentially use verbs as adverbials. The difference would show up in our punctuation, which might be a moot point given what is known of Klingon punctuation.
Example: {mer; SuvlaH verengan}
"Surprisingly, the Ferengi can fight." (Literally, "It surprises; the Ferengi can fight."
In speech of course, the semicolon would be audible only as a pause, if at all.
It might even be the source of adverbials. motlh; SuvlaHbe'
verengan it is usual: Ferengi cannot fight becomes motlh
SuvlaHbe' verengan Ferengi usually cannot fight. But
I tend to think not, or at least not quite so simply as this,
because so many adverbials are multisyllabic, and verbs very
rarely are.
