Words of Power for combos ?

So, the word of power for Flame Fist is "Ignis", but when I combo Flame Fist with my blades skill Thrust to create Smoldering Shiv, my avatar just uses it silently without speaking any logos.

But it seems to me he should, if words of power are necessary from a lore point of view in order to cast magic.

So there are two types of combos,

-Magic+melee combos. In this case, you would expect the caster to say the logos from the magic half of the equation, even as he uses it with his weapon !

- Magic+magic combos. In this case, either the two logos would need to combine, or a unique string might need to be created to avoid duplicate words. So, if say I wanted to combo Flame Fist with Ignite Weapon (just an example I have handy, not necessarily a meaningful spell), I would be combining Ignis with Ignis-Jura. A literal concatenation would be Ignis-Ignis-Jura, though, so maybe a unique string of words would be better.
