Does Latin allow the letter 'k' in suffixed words?

Actually, I'm explaining a phenomenon in which English spelling changes...

Consider the following examples:

Likeable, shakeable, makeable - these words are of Germanic origin. They do allow 'k' in words that are suffixed.

Now,

• Revoke + able -> revocable but not revokeable/revokable.
• Invoke + able -> invocable but not invokeable/invokable.
• Provoke + able -> provocable but not provokeable/provokable.

They're from Latin revocare, invocare, provocare respectively.

It has to do with their etymologies. They're of Latin origin.

My question is that 'does Latin allow the letter k in suffixed words?'

Or what's the reason for this? They allow 'c' in the suffixed words but don't allow 'k'. Why?
