I think the definition of 17 is the first 2 words with the wordplay being a reversal of the usual abbreviation for Alabama and a reversal of a three letter common word for everything.
The resulting name is not one I have come across but a Google search suggests it is a given name on Spain and France. Various meanings are given but one is “well spoken”. It may also be a contraction of Eulalia which means “sweetly spoken”.
Not sure if this really leads to talkative.
There may be a better explanation but this (just) works for me.
