Maybe you meant Category:Proto-Slavic verbs ending in a consonant?
It's common in grammars to leave out "ending". You often see things like "verbs in -i".
Oh. Still though, I think it would be clearer if it said that explicitly.
It's common in grammars to use ь and ъ, too. ;) I agree with Wikitiki that we should spell out "ending"... let's be grammatical and use verbs in our dictionary. :b
