And constructions like {Hoch 'ebmey} are treated as grammatically plural, as we have the Ca'Non {Hoch 'ebmey tIjon} (tkw p.51).

So, to summarize this thread:

{Hoch vIghro'} = each cat (to be treated as grammatically singular)
{Hoch 'ebmey} = all opportunities (to be treated as grammatically plural}

And (the subject of this thread), in order to say "someone sees all cats", we *have* to place the {-mey} on the noun after the {Hoch}, thus writing {Hoch vIghro'mey luleghlu'}.
