A NAME HAS TO SURVIVE BEING SAID OUT LOUD
Most names die in the same place: someone tries to say it in a noisy room and it comes out wrong. Before you commit, say your shortlist across a table to someone who has not seen it written down. If they ask you to spell it twice, it is costing you every time it is spoken.
Short beats clever. Two syllables beat four. A name that can be shouted has a real advantage over one that has to be explained, because the moment that matters is a stranger repeating it to another stranger.
