Stressed -ly

Have been pondering the probaBLY question and then today encountered basicalLY from someone, who was surprised that she'd uttered it when I called her attention to it. Clearly this is something only possible with single word utterances -- for that speaker and for me too (though I don't think I say this much). It's surely coincidence that both are three syllables -- likeLY must be possible for such speakers (though I didn't think to ask about it).
